Grey blue butterfly - Polyommatus icarus - Female
Brossard, Quebec, Canada
August 25, 2012
A grey blue butterfly, with orange markings on the outer rim of the lower wing. The upper surface of the wing was blue but it kept its wings closed when settled. I am a bit stuck, any help would be highly appreciated, thanks.

Moved from ID Request.

European Common Blue I think
This looks like the European Common Blue (Polyommatus icarus). A population, likely anthropogenic, was recently discovered in Quebec by Ara Sarafian.

Thanks for the help with this, it is very much appreciated. Following up on your info., according to the internet this species was first seen over here near Mirabel in Quebec, which is a large airport. Mirabel is about an hours drive from where this one was found.
