Stonefly? No: Nigronia serricornis

not a stone fly

the order Plecoptera, from the greek words plektos and pteron mean twisted wing. one thing you will notice when you see stone flies is that they are very narrow, if you may say, compared to Neuroptera (this guy). im pretty sure this is a fish fly. but ive been making alot of stupid mistakes lately, so wait for a confirmation on that

Alderfly?

Hi Peter, nice to see you here on Bugguide. Compare with these images in the guide.

i dont know

alderflies, the wings rest vertical to each other, unlike this guys wings which are laying on top of each other. i do agree with the order though

Maybe Corydalidae--Nigronia

I thought this was an Alderfly at first--good point about how the wings are folded. I think this must be a Nigronia, a "dark fishfly", but it sure is light-colored. Perhaps it has lost some scales. I see the white band on the wing, I think.

Very interesting.

yeah,

i did think the wings are why too light. they also lack the spots that Corydalidae have on their wings. i think it may have lost some scales, or it might have just frshly finished molting. interesting indeed

I uploaded another shot

Thanks, everyone! Nigronia looks good. I uploaded another view of the same specimen. In that one you can see a yellow oval stuck to its chin. I thought at the time that that was a mite, but maybe it's an egg?

BTW, I fixed the date -- these were taken around 5-6 PM on July 4th, not April 7th.

i think most of us think it i

i think most of us think it is in the genus Nigronia. however, we all agree it is a Corydalid
