Life of the Party
The orange is wing buds.....gills are white in the front and sometimes rear too.
Fixed it for ya! 😂Not unusual to see a bit of orange in the butt too especially on brown chironomids. The orange side of Uni-Mylar Peacock/Orange tinsel does that well.
All this is part of the fun of fishing chironomids. Basically all you need in spring is a good leech pattern, a good scud pattern and about 10,000 chironomids.
