Isonychia bicolor (Mahogany Dun) Mayfly Dun
View 6 PicturesThis is a naturally crippled female Isonychia bicolor dun. One of her main wings came out as a deformed, crumpled yellow object. I found her flopped over on her side struggling on the surface of a small stream.

Isonychia bicolor (Mahogany Dun) Mayfly Dun
View 6 PicturesI thought this dun was worth photographing, even though she's in pretty bad shape, because she shows something I haven't seen in Isonychia elsewhere. The bright stripe down the back which is normally present only in the nymph carried over to the dun in this one.
