Do you know what this insect is? I found it today (Nov. 11, 2011) on some leaves near my driveway. I live in Columbus, Ohio USA. It has what looks like a long, skinny head with a proboscis (though it is not a butterfly, clearly) and is large: approx 1-1/2" in length not counting the length of its feelers. And it has a ridged back (notable in the third picture). It crawls very slowly though that could be because it's cool (about 55 degrees F) and at the end of the season. I'd thought it was some kind of squash bug except any example I've found on the internet lacks this bug's long skinny head.

Any ideas?

Thanks!!
