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.
