I work at a local YMCA and some kiddos found this dude just hanging out on the side of a storage shed. Middle of the morning, really hot ouside, just happened today! I didn’t see him moving at all.. came back a couple of hours later to take another pic and he was only moved slightly. Thanks for your help!

Dear Ashleigh,
This is a male Dobsonfly, one of our most common summer identification requests.

Thanks for letting me know. What do they do? I can’t believe I’ve never seen one before in my life.. pretty crazy looking.

Dobsonflies are generally found not far from a source of water.  The larval Hellgrammites are used as bait by anglers.  Adult Dobsonflies do not eat, living long enough to mate and produce a new generation.  Male Dobsonflies have impressive mandibles that are ineffective in terms of biting to defend themselves, while female Dobsonflies have more utilitarian mandibles that could produce a pinching bite if carelessly handled, but they are still considered harmless toward humans.
