This is the "meal*worm" that could eat a lizard! When first handled he jabs his spiny urogomphi against my hand. I'm pretty sure this is one of the big coelo*metopine species since I don't know what else would get this large. Also, it very closely matches a larva I discovered in a rearing container three years ago in which I kept a coelo*metopine from the same local. It was apparently a gravid, mated female and she laid an egg that hatched, resulting in a larva that grew and grew but had an unsuccessful molt (probably due to heavy mite infestation) and didn't make it to adulthood.
