There are two Catalpa trees on the farm next door, in the middle of a field we make hay on. I mowed it last night and saw some half-eaten leaves. Went back tonight and found these guys:

BM, both of these trees had cigars (seed pods) and both of them had Catalpa worms. Maybe it's different with the Southern Catalpa? (There are two different spcies/subspecies).
These are the first CWorms I've seen since I was a kid (have been baling that field for 15 years, never looked in the trees). I'll be trying them out as bait tomorrow.
