Butterflies of Warwickshire, Coventry and Solihull
Common Blue
Polyommatus icarus


Not as 'common' as the name suggests, although some colonies still support large numbers.

The bright blue males are most easily seen while the brown or brown/blue females are more secretive in behavior.

A visit to a known colony late in the evening or during sunset provides the best opportunity to see this butterflt close-up as they tend to roost in groups on a dried grass stem, facing down, wings closed but one side face on to the sun to absorb as much heat as possible before the sun finally sets.

Larval Food plants
Common Bird's-foot-trefoil (Lotus corniculatus)

White Clover (Trifolium repens)
Lesser Trefoil (Trifolium dubium)


Habitat Requirements
The Common Blue is found in a variety of grassy habitats, particularly where the larval foodplants can be found in sunny sheltered positions such as roadside verges, woodland clearings, disused railway lines, quarries and post-industrial brownfield sites.
