    Got a visitor yesterday. Can't remember the last time I've seen a salmonfly at the house.

    Taxon: How does one ID adult salmonflies to species?

    Hi Matt-

    There are subtle differences in shape shape of genitalia, which can be examined with a microscope to identify adult Pteronarcys to species. Those "keys" would be available in the references listed on Ethan Bright's Aquatic Insects Of Michigan Pteronarcys Identification Keys page.

    The reason for the question was I saw some shell casings of bugs about that long stuck under a bridge on the Foss river. At the time I didn't know what they were. I guess I do now. Well maybe.

    Thanks Taxon. I should've guessed Scoones was harassing insects and their genitalia with microscopes.

    Although I realize you were just joking, I'm pleased that Chris chose to share his salmonfly photo with us, and appreciative of his having created this forum. How's that for sucking up? ;)

    I guess if one has studied moth balls one has the skill to sex salmonflies.

    I suggest posting a large sign on your boat that reads "Show us your Species." Well, on second thought..

    Matt,

    I had no microscope so my approach was a bit more hands on. I assure you that by the time I was done with my examination I had learned nothing but had gained a new friend.

    Chris

    No doubt that it's a great photo but if you want to get a shot that Mr. Flynt might publish you're gonna have to flip that baby over and zoom in a lot tighter.
