Anyone know what this is? Found it in the middle of an alpine lake in the north bend area a day ago. Water was still cold, just recently melted out. The lake does have a small stream that runs in and out of it. There were plenty of them on the lake, at first I assumed Callibaetis because it's a lake, but it definitely doesn't look like one. The dun is approximately a size 14.
You're right it's not a Callibaetis, looks like a new dun, looking at the tails. It looks familiar but not sure what it is, but I'm sure it came from the stream not the lake. Someone should be able to ID it with a little research. I'm curious as well.
It looks like a March Brown....not sure. I've seen a few of the same bug at Cady. That's what Bill and I called them....:hmmm:
March Brown (rhithrogena) have speckled wings. My guess is a leptophlebia male dun, commonly called Black Quills. In north Idaho they hatch in lakes in late spring/early summer. Taxon will let us know for sure...
Black quill was my guess as well, I didn't even know black quills existed in Western Washington though. Couldn't find much info about them on Google.
Looks like a bug I saw on a lake in the north bend area but I wouldn't consider this lake alpine. Black quill, interesting, learn something new everyday.
Hi Rory- Sorry it took so long to respond, but I've been out of commission for several days. creekx nailed the ID, as it's a Leptophlebia male dun (subimago), probably L. cupida.
