Field notes and information
A very local species of the Balkans.
Identification & Similar species: Very similar to the other clouded yellows, Colias. In the region, a rich orange upperside colouration helps separate it from the clouded yellow C. croceus which is lighter yellow-orange. The Greek clouded yellow C. aurorina has strong violet tones and the underside is much greener.
Distribution & Flight: Very local in Bosnia, Serbia, FYROM, N Greece and Bulgaria. It is a species of limestone mountains flying at mid to high altitudes (1200-2200m).
Single brooded flying in June and July, and into August at higher levels.
Habitat & Behaviour: A strong flier that pauses to nectar briefly. It inhabits rocky mountain grassland with abundant flowers on limestone. Larvae feed on broom species such as the Chamaecytisus shown below.
