In Paul Weamer's book (page 190) "Fly Fishing Guide to the Upper Delaware River" he writes "Some Upper Delaware Isonychias are bright green when they first emerge. They eventually change into their reddish purple to grayish pink color as they are exposed to the air". I'd like to tie some of these but would like to see a decent picture of the adult insect as it first emerges. Anyone have any pictures with the bright green abdomen?
