I had no idea that dobsonfly larva could be so big and not be totally submerged in water.
Awesome. Thank you!

Found this guy under a rock next to the Delaware river in New York State. It was about 3 inches in diameter after it balled up so it was big!
The iNat and Seek apps have no idea. Says it may be some sort of arthropod. I'm scouring my insect books...nothing.
Please help! I need to know what it is ...
