Baetisca+berneri
My Biology classes did a Leaf Pack activity on Friday and uncovered these macroinvertebrates which we have identified as armored mayflies. The may shows a couple of isolated areas in the Northeast but nothing in my area. To me it looks closest to Baetisca berneri but I could be off on this as I am no expert. What was neat was that I got these by taking a garden rake to a leafpack in shallow water an hour before school started and we examined the find. On November 15th!

Thanks for all the help, Eric. That was fun.
Yes! I think you've got it exactly right! Nice find by the way. As I said, I've never seen one like this. Probably due to my location. He's really cool though.
How about Baetisca berneri?

here's a source!
I don't think it's a stonefly as stoneflies have 2 tails. This looks like a mayfly, but not one I've ever seen before. It's also not in my guides. Upon some research I found a genus of armored mayflies (Baetisca), but it's hard to figure out the exact species. They do seem to be more prevalent in your area according to the map you've provided. Which would also explain why I have never seen one. haha I'd say it's definitely Baetisca, but as far as species it could be laurentina, obesa, or maybe even lacustris. Hope this helps!
