The blue butterfly

Blues, coppers, and hairstreaks are small butterflies. Many larvae associate with ants; adults nectar at flowers.

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

Theresia’s Blue is recorded from Turkey.

GBIF currently lists 25 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.

Theresia’s Blue is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
