About Pacific Cockroach
Pacific Cockroach (Euthyrrhapha pacifica) is a member of Corydiidae in the order Blattodea. Its recorded origin status on Kauaʻi is introduced / adventive.
Pacific Cockroach (Euthyrrhapha pacifica) is documented from Kauaʻi. Corydiid cockroaches develop through incomplete metamorphosis. Ecology varies from litter and soil-associated forms to species living in vegetation or human-modified habitats. On Kauaʻi, observations are most useful when they record microhabitat, activity period, nymph/adult stage and voucher morphology. 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.
Pacific Cockroach (Euthyrrhapha pacifica) is an adventive tropical cockroach recorded from Kauaʻi. It often occupies leaf litter, vegetation, and sheltered human-associated microhabitats.
Kauaʻi occurrence evidence: Hawaii Biological Survey states Euthyrrhapha pacifica was previously reported from Kauaʻi, Oʻahu, Maui, and Hawaiʻi.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; nymphal instars; adult; no pupa.
Habitat
Leaf litter, soil, bark, vegetation, buildings, or other sheltered microhabitats.
Food and ecological role
Generally omnivorous or detritivorous.
Reproduction
Eggs are enclosed in an ootheca; nymphs molt repeatedly before adulthood.
Movement
Walking is primary; adults of some species can fly.
Ecosystem role
Detritivore/omnivore.
Threats and impacts
Most impacts are localized; introduced species may become synanthropic.
Monitoring
Record microhabitat, activity period, nymph/adult stage and voucher morphology.
Classification note
The shared taxonomy follows the cached GBIF classification. Alternative placements reported in the source package are preserved in the record history.
