About Itodacne sordidus
Itodacne sordidus is a member of Elateridae in the order Coleoptera. Its recorded origin status on Kauaʻi is endemic — kauaʻi.
Itodacne sordidus is a Kauaʻi-endemic click beetle. Adult and wireworm-like larval stages are distinct and should receive separate identification coverage when larval material is species-secure. Click beetles undergo complete metamorphosis. Adults can snap the body at the thorax to right themselves; larvae are often elongate wireworms in soil, wood, or other substrates. On Kauaʻi, observations are most useful when they record larval substrate, host association, adult light attraction, and voucher specimens. Where island-specific host, prey, breeding-site, abundance, or seasonal information is not yet firmly documented, those details should remain tied to direct specimens and field observations rather than inferred from populations elsewhere.
Kauaʻi occurrence evidence: Historical/current Hawaiian elaterid keys identify Itodacne sordidus as a Kauaʻi species; ITIS retains the Itodacne spelling as valid.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; larva; pupa; adult.
Habitat
Soil, litter, dead wood, vegetation, and plant roots depending on species.
Food and ecological role
Larvae may be predators, detritivores, or root/seed feeders; adults often use plant material or nectar.
Reproduction
Eggs are placed near larval substrate; larvae may develop for extended periods before pupation.
Movement
Adults walk and fly; larvae remain substrate-associated.
Ecosystem role
Predator, decomposer, or herbivore depending on species.
Threats and impacts
Native endemics may depend on intact forest substrate; introduced wireworms can be crop pests.
Monitoring
Record larval substrate, host association, adult light attraction, and voucher specimens.
