Field notes and information

The rare sister species of the much more widespread and common green hairstreak, C. rubi. This species is unlikely to be encountered casually, but it is just possible throughout its range.

Identification & Similar species: Superficially very similar, some characteristics to separate C. avis vs C. rubi:

- Eyes ringed rusty orange vs white. If it looks remotely white, it isn't the current species.

- Inner side of antennal clubs rusty orange vs all black.

- Stripy legs white-brown vs white-black.

- Underside hindwing white stripe relatively further from wing margin vs closer.

Note: often the underside hindwing white stripe is quoted as being strong in avis but this is certainly not reliable feature.

Distribution & Flight: North Africa, southeast and northwest Iberian Peninsula and Mediterranean France. Usually near the coast in Europe. Very local across its range. One generation in late March and April. Said to fly into June at higher levels and in Morocco.

Habitat & Behaviour: Dry scrubland with larval food plant the strawberry tree, Arbutus unedo, and early spring flowers.

Variation: Underside white line very variable in intensity and continuity.
