Eastern Dobsonfly, Corydalus cornutus.
Photographed alive after briefly chilling in a refrigerator.
In her warmed-up state, she was more than a little intimidating.

GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist and her five parrots are currently relocating to Germany, where she will continue writing her blog while also writing a book and learning German. (Meanwhile, her parrots will continue to nibble on her extensive personal library.)

Now, that's a really nice specimen photo. I was trying to find the pin holding it down...

I just love dobsonflies. That one's a female, which could actually inflict a bit of a nip. The adult males have gigantic mandibles that are much less effective for biting.
Actually, C. cornutus probably does its best biting in the late immature stages; these are the ferociously predatory "hellgrammites" that are sometimes sold in bait shops. (I don't know whether the fish bite them or they bite the fish!) I once tried to pick up a full-grown hellgrammite with my fingers during an aquatic collecting trip in Michigan. The critter bit me so hard it drew blood from both sides of my thumb. Saved its own life, too, since I reflexively flung it back into the water rather than stuffing it into my killing vial!
