- Any live insects offered must be genuinely tiny — flightless fruit flies and pinhead crickets, not standard feeder sizesThis is the single biggest feeding mistake new keepers make with this species: reaching for the same crickets or dubia roaches sold for larger…
- Most homes don't need a dedicated heat source for this speciesMourning geckos generally do best at normal warm room temperature — roughly 75–82°F (24–28°C) — and can suffer heat stress above that, which is a…
- This species needs genuinely high humidity — roughly 60–80% — with good ventilationMourning geckos come from humid tropical coastal habitats and need consistent misting once or twice daily, paired with good airflow to stop that…
- A compact enclosure can comfortably house a colony, unlike most gecko species which need solo or carefully matched housingBecause same-sex aggression is largely absent between clonal individuals, keepers can house several mourning geckos together in a smaller footprint…
- Low-level UVB is increasingly recommended, though not strictly mandatoryGiven this species' shaded, foliage-dense natural habitat, mourning geckos don't have the strong basking-driven UVB dependency of a desert species.
- A secure, tightly fitted, fine-mesh lid is essential — gaps that are irrelevant for larger geckos are real escape routes hereGiven their small size, sticky toe pads, and jumping ability, even a small gap in a lid or door seam is a realistic escape route for this species…
- An established colony of adult females will lay fertile eggs regularly without any male presentThis is a direct consequence of parthenogenesis and something new keepers are sometimes surprised by — egg production isn't a sign anything unusual…
- Metabolic Bone Disease is preventable with a properly formulated dietMBD results from inadequate calcium or D3 intake, most often from feeding an incomplete homemade diet or unsupplemented live insects instead of a…
- Like all reptiles, mourning geckos can carry Salmonella without appearing sick themselvesThis is a general reptile-keeping risk, not specific to this species, but worth stating plainly: wash your hands after handling the gecko or cleaning…
- Mourning gecko skin is delicate and can tear or bruise if the animal is gripped tightlyGiven how small and light-bodied this species is, it should always be allowed to walk from hand to hand rather than being pinched or restrained…
- Watch for restlessness, appetite loss, or seeking out the coolest surface as early signs of heat stressProlonged exposure above roughly 82°F (28°C) can cause appetite loss and, in severe cases, loss of coordination.
- A quick daily visual check of eyes, vent, toes, and general alertness catches problems earlier than occasional weighing aloneBecause mourning geckos spend much of the day tucked into foliage, a brief low-disturbance look during evening activity is a practical way to monitor…
- Because adults weigh only a few grams, even a small absolute weight change can be significantA gram or two of weight loss that would be trivial in a larger reptile represents a meaningful proportion of a mourning gecko's total body mass — a…
- There is no selective-breeding morph market for mourning geckos the way there is for crested geckosBecause reproduction is parthenogenetic, offspring are clones of the mother rather than the product of two parents' genetics being combined and…
- Eggs are typically laid in pairs and glued firmly to a surface such as bark, a leaf axil, or the inside of an enclosureUnlike loose-laid eggs from many other reptiles, mourning gecko eggs adhere to whatever surface they're laid against almost immediately and are…
- Hatchlings are fully independent from the moment they emerge, with no parental careA newly hatched mourning gecko is essentially a miniature adult and begins hunting fruit flies and taking MRP on its own within the first days, so…
- Keepers who don't want an ever-expanding colony need a plan for eggs, since a healthy adult colony will keep producing themOptions range from simply allowing natural population turnover, to removing and discarding eggs, to rehoming surplus hatchlings — but given how…
- Mourning geckos belong to Gekkonidae, the true gecko family, unlike leopard geckos which belong to the eyelid gecko familyThis places them alongside other adhesive-toed, brille-eyed geckos such as crested and gargoyle geckos, in contrast to the clawed, moveable-eyelid…
- Lepidodactylus lugubris was formally described by naturalists Duméril and Bibron in 1836The species has been known to Western science for nearly two centuries, long before its parthenogenetic reproduction and remarkable global spread via…
- The species' parthenogenetic lineages are believed to have originated from ancient hybridisation between two related, sexually-reproducing Lepidodactylus speciesThis process, called hybridogenesis, is thought to have produced the clonal reproductive mode seen today, with different resulting lineages varying…
- Mourning geckos have been studied by scientists since at least the 1960s as a model species for understanding vertebrate parthenogenesisBecause true parthenogenesis is rare among vertebrates, this species' reliably all-female reproduction has made it a long-standing subject of genetic…
- In the wild, mourning geckos eat a mix of nectar, pollen, tree sap, and small invertebrates such as ants, moths, and spidersThis broadly omnivorous natural diet is reflected in captive care, where a complete nectar-based powdered diet supplemented with tiny live insects…
- Flightless fruit flies, particularly the slightly larger Drosophila hydei, are commonly preferred over the smaller Drosophila melanogaster for feeding mourning geckosThe larger species offers more nutritional value per insect while still being small enough for even a hatchling to safely eat, making it a popular…
- Springtails make a suitable supplemental live feeder for the very smallest hatchling mourning geckosTheir tiny size suits animals barely larger than a grain of rice, and a springtail population established in a bioactive substrate can provide an…
- A tall, front-opening bioactive vivarium with dense live planting suits mourning geckos better than a wide, low enclosureBecause the species is highly arboreal and rarely descends to the ground, vertical space and climbing surfaces matter far more than floor area…
- A mature female mourning gecko typically lays a new pair of eggs roughly every two to four weeks once established in good conditionsThis frequent, ongoing egg production is a direct consequence of parthenogenesis and continues indefinitely in a healthy colony unless eggs are…
- Mourning gecko eggs typically take roughly 40 to 90 days to hatch, depending on ambient temperatureBecause eggs are usually left glued in place within the vivarium rather than moved to a dedicated incubator, hatch timing varies more with a room's…
- Multiple females in a colony often glue their eggs to the same favoured surface, creating a shared communal egg-laying siteThis clustering behaviour has been documented in both wild and captive populations and means a single well-used leaf, piece of bark, or enclosure…
- Female mourning geckos commonly reach sexual maturity at around four to six months of age in captivityThis relatively fast maturation, combined with parthenogenetic reproduction, allows a small starting colony to expand its numbers considerably within…
- Mourning gecko hatchlings look like miniature adults from the moment they hatch, without a distinct juvenile colour phaseUnlike some gecko species that show a strikingly different juvenile pattern that fades with maturity, mourning gecko hatchlings display essentially…
- A mourning gecko's somewhat translucent belly can let a keeper see visible fat bodies, a useful tool for judging body conditionSimilar to the translucent-bellied appearance seen in some other small gecko species, this lets an attentive keeper get a rough visual sense of an…
- Mourning geckos should never be deliberately cooled or brumated, unlike some temperate reptile speciesComing from a consistently warm, humid tropical and coastal environment, this species has no natural cold-season dormancy period, and prolonged cool…
- Because mourning geckos weigh only a few grams, pesticide or fertiliser residue on live plants used in a bioactive setup poses a proportionally greater risk than it would for a larger reptileAny live plants added to the enclosure should be thoroughly rinsed and, ideally, sourced from a pesticide-free supplier, since a dose of residue that…
- Research into gecko chemical ecology suggests mourning geckos may use scent cues to recognise related, genetically identical colony membersBecause every individual within a clonal lineage shares essentially the same genome, some studies of social gecko species have explored whether…
- Mourning gecko droppings are tiny enough that a magnifying loupe is genuinely useful for checking consistency and colour during health monitoringGiven the species' very small body size, subtle changes in such small fecal output can be hard to assess with the naked eye alone, making basic…
- Minor damage to a mourning gecko's toe pad setae can be repaired over the following one or two shedsAs with other adhesive-toed gecko species, temporary reductions in grip from debris or minor wear at the toe pads typically resolve as the outer…
- A regrown mourning gecko tail is typically shorter, smoother, and slightly different in colour from the originalThis is a normal, permanent cosmetic difference following tail regeneration and doesn't affect the gecko's health, mobility, or ability to climb and…
- Even in a genetically identical, low-aggression colony, larger or older individuals can still get first access to food over smaller, younger geckosThis size-based, rather than dominance-based, feeding order is a subtler form of competition than the outright aggression seen in many other gecko…
- Mourning gecko eggs have a harder, more calcified shell than the soft, leathery eggs of ground-dwelling geckos like the leopard geckoThis firmer, adhesive eggshell type is typical of many true gecko species (Gekkonidae) and is part of why the eggs can be glued firmly to a surface…
- Because mourning gecko eggs are firmly glued to a surface, most keepers leave them in place within the vivarium rather than moving them to a separate incubatorThis differs from species with loose, unattached eggs that are commonly relocated to a controlled incubation container, and it's part of why a…
- Mourning geckos are studied in invasion biology as a model species for understanding how reptiles establish populations through human-assisted transportTheir parthenogenetic reproduction, small size, and tolerance of shipping conditions make them a particularly useful case study for researchers…
- Mourning geckos have not been individually assessed by the IUCN in the same way many less widespread reptile species haveGiven how broadly established the species is across its introduced and native range, it isn't considered at any conservation risk, and most…
- Mourning geckos are not listed under CITES and can be traded and kept without special import or export permits in most jurisdictionsThis, combined with the species' ease of captive breeding through parthenogenesis, is part of why it's widely and inexpensively available in the…
- Because mourning geckos are unusually social for a gecko species, housing a single individual alone can lead to more stress and reduced activity than housing a small colony togetherUnlike most gecko species, which are typically kept solitary to avoid territorial conflict, this species tends to do better in the company of others…
- Providing more than one feeding station or perch near food sources helps reduce competition for fruit fly cultures and powdered diet access in a colony setupAs a colony grows, a single feeding point can become a bottleneck, so spreading multiple small feeding dishes or ledges around a vertical enclosure…
- Good airflow remains essential in a mourning gecko enclosure even though the species needs high humidityDense live planting and frequent misting in a small, poorly ventilated enclosure can allow stagnant, overly damp conditions to develop, which raises…
- Mourning geckos primarily hydrate by drinking water droplets left on leaves and enclosure surfaces after misting, similar to crested geckosA standing water dish is optional rather than essential for this species, since regular misting combined with the moisture content of a complete…
- Any bioactive cleanup crew used in a mourning gecko enclosure should be genuinely small-bodied, since larger isopods can compete with fruit flies for food and spaceSpecies like dwarf springtails and small isopod varieties are better suited to this scale of vivarium than the larger cleanup crew species sometimes…
- Mourning geckos are sometimes sold cheaply or informally as 'feeder' or 'starter' geckos, though they warrant the same standard of care as any other pet gecko speciesTheir low price and easy availability shouldn't be taken as a sign that proper humidity, temperature, diet, and enclosure size matter any less than…
- A mourning gecko's flexible body can compress through gaps that look far too small for an animal of its sizeThis makes enclosure security an even higher priority than the animal's measured body size alone would suggest, particularly around ventilation…
- Mourning geckos are generally considered a display species best minimally handled, rather than a species suited to frequent handling like some larger geckosTheir small size, delicate skin, and jumping speed make routine handling more stressful and physically risky for the animal than for hardier…
- Because mourning geckos mature quickly and reproduce without needing to find a mate, even a small starting colony can expand its population noticeably within a year or twoThis rapid, low-barrier population growth is part of why keepers who don't want an ever-expanding colony need an active plan for managing eggs from…
- Wild mourning geckos face predation from birds, larger geckos, and centipedes that captive individuals never encounterAs with many small reptiles, removing these predation pressures in captivity is a major contributor to the gap between typical wild survival and the…
- Captive mourning gecko colonies show little to no courtship-related behaviour compared to sexually reproducing gecko speciesBecause reproduction doesn't require attracting or securing a mate, the elaborate courtship displays, tail-shaking, or biting behaviours seen in…
- The mid-20th century saw a marked acceleration in the mourning gecko's global spread, coinciding with a large increase in Pacific shipping and cargo movementResearchers studying the species' introduced range point to increased vessel traffic and cargo transport across the Pacific during this period as a…
- Different clonal lineages of mourning gecko have been observed to show slightly different thermal or humidity tolerancesBecause each lineage is a distinct, long-established clone, subtle physiological differences between lineages are plausible and have been noted…
- Mourning geckos don't perform the slow pre-strike tail wave seen in some ambush-hunting gecko speciesTheir foraging style leans more toward direct pursuit of small insects and lapping nectar or soft food than the stalk-and-strike ambush hunting…
- Mourning geckos tend to produce fecal output relatively frequently for their size, consistent with a fast metabolism supporting frequent small feedingsBecause the species typically eats small amounts often rather than large infrequent meals, more frequent, small droppings are a normal pattern rather…
- A new mourning gecko colony can be started from a single female, unlike sexually reproducing pet gecko species that require both a male and femaleBecause of parthenogenesis, one female is capable of founding an entire self-sustaining colony over time, a genuinely unusual starting point compared…
- Mourning geckos show a comparatively weak seasonal breeding cycle compared to species from more temperate climatesComing from an equatorial and tropical native range with less pronounced day-length and temperature seasonality, egg production in this species tends…
- Juvenile mourning geckos shed more frequently than adults, in line with their faster early growth rateAs with many gecko species, the shedding cycle slows once a gecko approaches adult size, though a humid enclosure remains important at every life…
- Finding a vet equipped to examine or treat an animal as small as a mourning gecko can be genuinely difficult, even among reptile-experienced practicesGiven the practical challenges of examining and dosing medication for an animal weighing only a few grams, many health decisions for this species…
- Keepers who want to limit colony growth often remove and discard eggs promptly after they're laid, since the firmly glued eggs can't easily be relocated insteadBecause eggs adhere tightly to whatever surface they're laid on, population management in this species usually comes down to either allowing eggs to…
- Mourning geckos, like most true geckos, show no externally visible parietal 'third eye' on top of the headThis light-sensing structure is more associated with certain other lizard groups; in mourning geckos and most Gekkonidae, light-cued rhythms are…
- A mourning gecko will lick its own eye to clear away dust or debris caught under its fixed transparent brilleBecause the species has no moveable eyelid, this self-cleaning tongue behaviour is the primary way it keeps its eyes clear, and is a normal…
- Like several other gecko species, mourning geckos almost always lay exactly two eggs per clutchOccasionally a single egg is laid instead of a pair, but a two-egg clutch is the standard, consistent output of a mature, actively reproducing female…
- Mixed powdered nectar diet offered to mourning geckos should generally be replaced within a day or two to avoid spoilage in a warm, humid enclosureBecause the diet is mixed with water and the enclosure is kept warm and humid to suit the gecko, uneaten food can spoil relatively quickly, making…
- Mourning geckos reproduce via a form of parthenogenesis called automictic thelytoky, producing genetically near-identical female offspringThis means offspring are essentially clones of the mother, aside from rare mutations, which is why colony members often look strikingly similar..
- Despite reproducing asexually, the mourning gecko species complex contains multiple distinct genetic clonal lineages with different characteristicsDifferent lineages can vary slightly in size, coloration, or behavior, though within a single lineage individuals are highly genetically similar..
- A small colony of mourning geckos, commonly 3-6 individuals, is often recommended as a manageable starting group sizeBecause eggs and hatchlings accumulate quickly in an established colony, starting smaller makes population management easier for new keepers..
- An unmanaged mourning gecko colony can grow substantially within a year given how frequently females lay eggsKeepers who don't want unlimited population growth need a plan such as removing eggs, culling clutches, or rehoming offspring regularly..
- Mourning gecko hatchlings emerge fully independent and can begin eating tiny food items within their first day or twoNo parental care is provided, and hatchlings are typically raised in the same enclosure as adults without issue given the species' social nature..
- Eggs are laid in adhering pairs that are glued firmly to a chosen surface such as cork bark, leaves, or the enclosure glassBecause the eggs bond tightly to whatever surface they're laid on, they are generally left in place to incubate rather than moved to a separate…
- Mourning gecko eggs typically develop and hatch within roughly 60-120 days depending on ambient temperatureWarmer room temperatures generally shorten this incubation window, similar to the temperature-development relationship seen in many other gecko…
- Mourning geckos are believed to have spread across much of the Pacific partly through human shipping activity over centuriesTheir parthenogenetic reproduction means a single stowaway individual can establish an entirely new population without needing a mate..
- The mourning gecko's likely region of origin is southeast Asia and nearby Pacific islands, though its exact ancestral range is debated given its extensive spreadThe species' long history of human-assisted dispersal makes pinpointing a single original native range more difficult than for many reptile species..
- While unusually social for a gecko species, mourning geckos in an overcrowded enclosure can still show increased stress and competitionProviding enough hides, feeding stations, and climbing surface per individual remains important even in a naturally colonial species..
- Mourning geckos produce a range of audible clicks and chirps used in social interaction beyond simple distress callsThese vocalizations are thought to play a role in colony communication, which is less commonly documented in less social gecko species..
- Flightless fruit flies are commonly used as a live insect supplement for mourning geckos given their appropriately tiny sizeBecause mourning geckos are so small, most standard feeder insects like crickets are far too large, making fruit flies, springtails, or pinhead-sized…
- Commercial meal replacement powders (MRP) formulated for small nectivorous or omnivorous geckos can serve as the core diet for mourning geckosThese products are typically mixed with water into a paste and offered on a small dish or ledge, similar in concept to crested gecko diet powders..
- In the wild, mourning geckos are known to feed on nectar, pollen, and fruit in addition to small insectsThis dietary flexibility is part of why a complete powdered diet supplemented with occasional insects works well for the species in captivity..
- A relatively compact vertical enclosure, sometimes as small as a few gallons per individual, can comfortably house a mourning gecko colonyThis contrasts with most other pet gecko species, where colony housing at this density would be considered overcrowded or a welfare risk..
- Mourning geckos routinely eat their own shed skin almost immediately after it comes off, more consistently than some other gecko speciesThis behavior likely helps recycle nutrients and reduces the chance of leaving noticeable shed debris in a shared colony enclosure..
- Visual sexing methods used for most reptile species don't apply to mourning geckos since the population is functionally all-femaleThe occasional rare male that appears is not typically involved in reproduction in a meaningful way, since the species reproduces via parthenogenesis…
- A dropped mourning gecko tail typically regrows within a matter of weeks, faster than the multi-month process in some larger gecko speciesThe smaller original tail size and higher overall metabolic rate of this small species are thought to contribute to a relatively quick regrowth…
- Balancing high humidity with adequate cross-ventilation prevents the mold and stagnant air issues that can develop in small, densely planted mourning gecko enclosuresMesh paneling or vents on opposite sides of an enclosure help maintain airflow even while misting keeps humidity elevated..
- Mourning gecko vivariums commonly use small broad-leaved tropical plants like pothos, pilea, or small bromeliadsDense, leafy planting supports the species' arboreal, hiding-heavy lifestyle and gives multiple basking-adjacent perches within a compact space..
- Physically removing and discarding eggs shortly after laying is one straightforward way keepers control mourning gecko colony population growthBecause eggs are laid in fixed, adhered locations, they can often be scraped off with a razor blade or similar tool before hatching if population…
- At roughly 5-8 years, typical mourning gecko lifespan is shorter than many popular pet gecko species like leopard or crested geckosTheir small body size and correspondingly faster metabolism are commonly cited as contributing factors to this comparatively shorter lifespan..
- Adult mourning geckos typically weigh only 1-2 gramsThis extremely small body mass means even minor weight changes can represent a meaningful percentage shift, making careful, consistent monitoring…
- Even though UVB isn't considered mandatory for mourning geckos, low-level UVB exposure is increasingly offered as a beneficial additionThis mirrors the broader trend in gecko care where species historically kept without UVB are now often given a low-output source as a…
- Mourning geckos can squeeze through remarkably small gaps given their tiny body sizeEnclosure lids and vent openings need noticeably finer mesh or tighter seals than would be sufficient for larger gecko species..
- Mourning geckos primarily drink water droplets left on leaves and enclosure surfaces after mistingA standing water dish is sometimes provided as a backup, but observed drinking behavior in this species centers heavily on post-misting droplets..
- Because all individuals in an established colony are genetically near-identical females, mourning gecko groups show less overt dominance hierarchy behavior than mixed-sex groups of other speciesMinor competition over food or favored basking spots can still occur, but the aggressive territorial displays seen in male-heavy groups of other…
- Bioactive setups with live plants, leaf litter, and a springtail/isopod cleanup crew are a popular and practical choice for mourning gecko enclosuresThe small size of the animals and their waste makes a self-managing bioactive system particularly well suited to reducing manual cleaning frequency..
- Mourning geckos are commonly offered food (MRP diet and/or fruit flies) every day to every other day given their small size and higher relative metabolic needsBecause individual portions are tiny, frequent small feedings suit the species better than large infrequent meals..
- Grabbing a mourning gecko by the tail during an attempted handling is a common and largely avoidable trigger for tail lossBecause mourning geckos are typically kept as a colony display species rather than handled routinely, minimizing direct handling in general reduces…
- Different mourning gecko clonal lineages are sometimes informally distinguished in the hobby by subtle differences in size or coloration, though formal lineage identification requires genetic testingMost keepers simply refer to their geckos as mourning geckos without knowing their specific clonal lineage, since visual differences between lineages…
- Mourning geckos, like several other gecko species, may use vent-area scent marking as part of colony-level communicationThis behavior is considered a normal part of social and territorial signaling within an established colony rather than a sign of a problem..
- Freshly laid mourning gecko eggs are initially soft and harden within roughly a day of being laidAttempting to move eggs before they've hardened risks damaging them, which is another reason many keepers prefer to leave eggs in place on their laid…
- Most mourning geckos kept at typical indoor room temperature (around 72-80°F/22-27°C) don't need a dedicated heat sourceKeepers in unusually cool climates or rooms may still add gentle supplemental warmth, but it isn't a default requirement the way it is for many…
- Impaction risk from substrate ingestion is considered relatively low in mourning geckos given how small their bite-sized prey items already areThis doesn't eliminate the value of choosing substrate thoughtfully, but the risk profile differs somewhat from larger insectivorous gecko species…
- New mourning geckos, including wild-caught or unknown-origin individuals, are generally quarantined before joining an established colonyEven though the species is often colony-kept, introducing an unquarantined new individual still carries the usual risk of introducing parasites or…
- A quick visual check of eyes, vent, toes, and general alertness across a colony helps a keeper notice if one individual is falling behindIn a group setting, a single unwell gecko can be easy to overlook amid normal colony activity unless keepers check individuals periodically..
- Assessing body condition in a species this small relies more on overall alertness, activity, and feeding participation than visible fat reservesUnlike species with an obvious fat-storage tail, mourning geckos don't offer as clear a single visual body-condition marker, making behavior a more…
- Springtails and small isopod species are commonly used as a cleanup crew in mourning gecko bioactive vivariumsBecause mourning geckos themselves may occasionally eat very small isopods or springtails, keepers sometimes choose a slightly larger or…
- Mourning geckos combine strong jumping ability with their small size, making them notably difficult to recapture if they escape an open enclosureKeepers commonly recommend working with the enclosure lid mostly closed and having any planned interaction happen inside a contained space to reduce…
- A consistent roughly 12-hour light and dark cycle is commonly recommended for mourning geckos even without a UVB requirementStable lighting supports normal activity and feeding rhythm regardless of whether UVB is included in the setup..
- Any live insects offered to mourning geckos as a supplement to a complete powdered diet are typically lightly dusted with calcium powderThis mirrors general reptile feeder-insect supplementation practice, adjusted for the very small quantities involved given the tiny size of…
- Lepidodactylus lugubris is technically considered a species complex rather than a single simply defined species, given its multiple genetically distinct lineagesOngoing taxonomic research continues to examine whether some lineages warrant classification as separate species in the future..
- Mourning geckos are generally considered better suited to being observed than frequently handledTheir small size and fragile skin, combined with a strong startle-jump response, make hands-off colony-watching the more common keeping style…
- An established colony will often lay eggs across a variety of surfaces throughout the enclosure rather than a single dedicated egg-laying spotThis differs from species that use a specific moist lay box, since mourning gecko eggs adhere directly to whatever surface a female chooses at the…
- Because of their small body mass, mourning geckos can lose or gain heat more quickly than larger reptile species when ambient temperature shiftsSudden temperature swings in a room are worth monitoring more closely for this species than for a larger-bodied gecko with more thermal mass..
- A drainage layer beneath the substrate helps prevent waterlogging in a regularly misted mourning gecko bioactive enclosureWithout adequate drainage, excess moisture from frequent misting can accumulate and contribute to mold or root rot in a planted setup..
- Providing more than one feeding dish or station in a colony enclosure reduces competition among multiple geckos feeding at onceThis simple setup choice helps ensure less assertive individuals in the colony still reliably access food..
- Audible clicking sounds in mourning geckos are most often reported during social interactions or when a gecko is startledThis is one of several vocal gecko species where sound plays a more documented communicative role compared with typically silent gecko species..
- In some regions where mourning geckos have become established outside their original range, they compete with native gecko species for food and habitatThis ecological impact is part of the broader conversation around invasive reptile species spread via human trade and transport, distinct from their…
- Providing multiple small humid hides at different heights suits a colony better than a single shared hideBecause the species is colonial but individuals still benefit from personal retreat space, spreading hides throughout the enclosure reduces crowding…
- Researchers describe the mourning gecko as having one of the broadest global distributions of any terrestrial reptileA 2026 review in the journal NeoBiota examining L.
- The idea that 'mourning' refers to the species' all-female biology is very likely a later folk explanation, not the original naming reasonResearchers note the Latin epithet lugubris ('mournful' or 'dusky') almost certainly describes the gecko's subdued colouration, since it was given in…
