Female Isonychia bicolor (Mahogany Dun) Mayfly Dun Pictures



 This 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.

This mayfly was collected from the West Branch of Owego Creek on August 22nd, 2006 and added to Troutnut.com on August 23rd, 2006.
