Sphenophorus destructor Chittenden, probably a new state record. Often a serious corn pest. Excellent photos.

thanx for the dorsal, Abby
I now wonder if this could be S. melanocephalus (that i've never seen); let's wait for more opinions

dorsal view is all-important -- pls add, and we'll figure it out
btw, why did you put it the anthribids? this is indeed a rhynchophorine (Curculionidae: Dryophthorinae: Rhynchophorini), more specifically, a billbug -- a member of the genus Sphenophorus

oops
I clicked on the wrong spot. Thanks! I'm not sure how to move it, but I'm sure someone on here will be able to help me out. I have added a dorsal view. Sorry about the pin hole!
