Plebejus idas

In the summer of 2014, a fire in Vastmanland in South Central Sweden affected an area of 13,100 ha.

[6] This species can be found in most of Europe (except parts of Spain, southern Italy and the United Kingdom),[7] in the northern regions of the Palearctic (Siberia, mountains of South Siberia and Yakutia) and in the Nearctic realms.

The upperside of male's wings is iridescent blue, while it is brown with orange submarginal spots in the females.

[10] The species flies in a single brood from June to August depending on location.

[9] The larvae feed on Calluna vulgaris, Vaccinium uliginosum, Empetrum nigrum and various Fabaceae species (mainly Cercis siliquastrum, Melilotus albus, Lotus corniculatus, Cytisus, Genista tinctoria, Trifolium pratense, Chrysaspis campestris, Astragalus alpinus and Anthyllis).

The female butterflies will lay the eggs on the host plant stems or debris (Bálint, 2020).
