4 inch nasty smelling ugly bug - Corydalus cornutus - Female
Limerick, Montgomery County, Pennsylvania, USA
June 28, 2007
Size: 4 inches long
We caught this at work outside. It landed on the wall. I've never seen anything like it. We are a mile or so from the neuclear plant. We gave it water and small tomato piece which it ate. Its mouth is between the two long pinchers which seem to be for show. It had a large body and at the end of it's tail it had what looked to be short pointed objects.

Male Dobson Fly
The scientific name for this fairly common critter is Corydalus cornutus. Those huge jaws on the males are used in mating, but the female has more useful jaws for biting and she will bite for defense. It is very interesting that you say your specimen at a piece of tomato because it is generally believed that Dobson Flies do not eat as adults.

Describing this neat looking insect as "ugly" in the title seems strange to me. Ugly is a very relative term.
