Hey there.
We found this “blue fly with a fur coat” flying around our yard. Any idea what it might be? We live in Chelsea, Québec ,Canada. Love your site! It’s super useful. Thanks for your help,
Celine & Marc

This is a Woolly Aphid in the genus Eriosoma. The winged ones are males.

Females can also have wings. In fact, the females are the most likely to have wings.
