Isos with green edged wings 3 Replies »
I have seen Isos with the forward edge of their wings an olive color. These were also on the upper East Branch. I tied some using a permanent marker to tint the leading edges olive. But, it seems that the standard pattern works as well.ReplyIso dun 16 Replies »
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? Reply
