I think the first weevil I ever heard about was the infamous boll weevil, scourge of cotton crops everywhere.
However, this is not a ‘boll’ weevil, but a ‘bowl’ weevil…
The largest weevil I have ever seen (about 16mm), this Lepyrus sp. was found feeding on the leaves of trembling aspen in Elk Island National Park, Alberta.
Thanks to BugGuide for the ID.
