Stonefly and Hellgrammite
I noticed that on your website that you did not have any pictures of the Common Stonefly adult or a Dobsonfly Larvae. I have included a picture of each for your records.
Thanks for the images. You must be a fisherman with all those Hellgrammites for bait. We actually have a Hellgrammite page seperate from our Dobsonfly page. The Common Stonefly looks like one of the Green-Winged Stoneflies in the Family Isoperlidae.
