Field notes and information

A distinctive species, rather unlike any of the other blues. It very occasionally reaches the UK where I was very fortunate to find one in the summer of 1998 on the south coast of Kent.

Identification & Similar species: A long tail on the hindwing separates this spices from most of the other blues. The uniform underside ground colour and a strong white submarginal streak confirms it. In flight it looks steely grey rather than blue.

Distribution & Flight: North Africa and Mediterranean Europe. Strongly migratory, it reaches northwards to north Germany. Occasionally reaching south England. It flies most of the year in the most southerly climes, migrating northwards as the season progresses.

Habitat & Behaviour: Very hot flowery places, particuarly with the larval food plants such as various pea plants, broom etc., Leguminosae . Often found flying very rapidly around stands of these plants where it can be quite numerous.
