This is a DOBSONFLY

[dalthauser]

I saw this on the wall of the outside of a Tetco the other day.  Huge - about 4 incles or more even.  I asked for an ID at Davesgarden.com and they said it was a Dobsonfly.  Apparently it's not a pest - adults live only 2 weeks - and the makes use those giant pincers (sickles)  to stimulate the female (not kidding).  From wheat I can tell the one I saw was a common Dobsonfly, but it looked anything but that to me :-)
