Soyedina vallicularia

two males, two females. Very nice. Lloyd was correct about the family - I must pay more attention to the wing venation. When in front of me the size itself (smaller than taeniopterygids) indicated the family.

Thanks Lloyd

I'm saving it for Don, so maybe we can find out which one it is.

Looks like...

a nemourid.

I am

leaning toward taeniopterygids, but I am not about to proffer a generic id! Possibly Boloto*perla, but if not it must be a nemourid.

Donald...

Here are my reasons for suggesting Nemouridae:

1. The veins in the costal space form an "X" with the other veins.
2. The convergence of the A1 and A2 veins before the margin of the forewing is a trait of some nemourids, but I have never noticed it in taeniopterygids.
3. The short second tarsal segment seems to show (albeit indistinctly) in Tom's related photo here.
4. They have slightly more bulbous eyes and shorter antennal scapes (when compared to many taeniopteryrids).

Lloyd:

You are probably correct, you've thought about it much more than me, but I must wait until it is placed in my hand before I will think about it further. Meanwhile up near Franconia catching Isogenoides, Taenionema and other delightful spring stoneflies (nemourids too, but I won't think about putting names on them until back at the lab).

I'm eager to see them, Donald

Between your work and Tom's photos, the growth in the stonefly, caddisfly, and mayfly pages has been fascinating to see. Many thanks to both of you!
