Field notes and information

A butterfly of flowery grasslands and clearings amongst bushes and trees. Usually local but widespread.

Identification & Similar species: Can be confused with the other short tailed blues plus the small blues. The presence of orange spots on hind wing is usually sufficient for identification. These can sometimes be present in the Provencal short tailed blue, E. alcetas, but the orange doesn't fill the space between the chevrons and the spots.

Distribution & Flight: Northern Spain, France and eastwards to Greece and the Balkans including most of Italy. Typically double brooded flying in spring (end of April to June) and then in summer (July and August).

Habitat & Behaviour: Grassy flowery places, possibly with light scrub or the edge of woodland. Often flies low and inconspicuously amongst vegetation.

The broad orange patches on underside hindwing separates this species from E. alcetas and decoloratus.
