European Common Blue (Polyommattus icarus)

A small butterfly species with intense blue color on the back of the wings and beautiful pattern on the lower side of the wings, It is an European species introduced in the Mirabel Airport region and now frequently observed in Montreal and surrounding area.

How To Identify

There are similar species with the intense blue color of the wing, endemic to the region. I identify this species based on the pattern of black and orange spots on the underside of the wings.

I have been able to spot this species in different parks in Montreal. Usually late summer, early autumn.
