Head-clipping Weevil - Haplorhynchites aeneus

Head-clipping Weevil - Haplorhynchites aeneus
Blackwell Forest Preserve, DuPage County, Illinois, USA
July 19, 2009
Size: 7mm
These weevils were abundant and all over everything, including milkweed.
I now find they are commonly called "sunflower head-clipping" weevil.
I did find them primarily on plants in the sunflower family.

Head-clipping
Now I see the category, I have to comment - all the plants this weevil was infesting had their heads clipped. It's amazing this insect causes such a specific damage.

And, speaking of which, the stem in the picture has been clipped.
