Mourning Gecko

Names and classification

Scientific name

Lepidodactylus lugubris

Common names

Mourning Gecko

Family

Gekkonidae

Kauaʻi occurrence and status

Kauaʻi occurrence

Present

Origin

Introduced

Conservation status

Not assessed

Evidence limits

Occurrence is supported; local abundance and impact estimates remain less certain than presence.

Habitat and ecology

Habitats

Terrestrial lowland habitats including vegetation, leaf litter, rock, woody debris, and developed areas depending on species.

Food and resource needs

Small arthropods and other invertebrate prey.

Reproduction

Parthenogenetic reproduction; eggs deposited in protected crevices and structures.

Shelter

Bark, foliage, rock, litter, crevices, walls, or woody debris depending on species.

Threats and conservation

Threats

Long-established nonnative gecko; competition with later-arriving house geckos and predation on arthropods occur, but Kauaʻi-specific conservation impact is not fully resolved.

Conservation actions

Early detection, containment/control where feasible, prevent intentional release or transport, protect high-value native habitats, and monitor ecological effects.

Monitoring

Repeat island occurrence surveys, population trend monitoring, and impact studies using standardized methods.

Data gaps

Current population distribution, abundance, and Kauaʻi-specific ecological effect sizes remain incompletely quantified.

Process and seasonal context

Seasonal timing

Generally year-round in Hawaiʻi; local activity varies with temperature and moisture

Seasonal description

Mourning Gecko (Lepidodactylus lugubris) is a documented established nonnative species on Kauaʻi.
