Polyommatus fabressei Oberthür, 1910

Host plants:
The larvae feed on Onobrychis species.

Habitat:
Polyommatus fabressei inhabits grasslands, bushy slopes, garrigues and similar dry-warm habitats in medium high altitudes between 800 and 1600m asl.

Life cycle:
The egg or the small caterpillar hibernate. The adults occur especially in July and early August, but also in late June and still to mid-August.

Remarks:
Polyommatus fabressei is endemic to Spain (more eastern and northern parts). I observed it in the mountain ranges of Castellòn and in the Sierra de Albarracin.
