Endangered
Biak Dark Crow
Euploea albicosta
Biak Dark Crow is a brush-footed butterfly in the family Nymphalidae (order Lepidoptera) — Euploea albicosta, recorded as Endangered and tied to Indonesia.
The brush-footed butterfly
It was first described by James John Joicey ug Alfred Noakes in 1915.
Brush-footed butterflies hold the first pair of legs reduced. The family includes fritillaries, admirals, and crows.
Moths and butterflies have scaled wings and a four-stage life: egg, caterpillar, pupa, adult. Most named species are known from a handful of specimens and a type locality.
Range and habitat
Biak Dark Crow is recorded from Indonesia.
GBIF currently lists 7 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
The adult is what most collections hold. The larva — the feeding stage — is often undescribed for the rarest names.
Life history follows the order: complete metamorphosis in moths and beetles, nymphs in grasshoppers and bugs. This page does not invent a host plant that no source named.
In crisis
Named moths and butterflies with a high threat category are often known from a small range and a thin series. Host-plant loss leaves little to recount.
