I came upon a source (stillwater blog re chironomid presentation) this week and then lost it to credit here…the site mentioned fishing patterns (they were talking about chironomid pupa patterns) in the often frequent algae bloom on/in lakes. The writer mentioned something interesting: the algae will taint/tint/paint your chironomid patterns that have antron or similar wings, gills, filaments. The writer suggested that a white bead would be a better substitute for the oft used white synthetic elements that extend above the bead, over the eye or horizontally beneath a wingcase, out to the sides. Something to consider. The algae bloom often only extends 5-10′ beneath the surface. A pattern can be presented below the bloom. But, drawing the the pattern through the bloom will coat the pattern with a green film. So, a simpler pupa pattern that can be swished clean is a suggestion. For all the others?….might as well stay with olive as the color theme? Anyway, I thought it an interesting suggestion for later in the Summer on stillwaters with a bloom.
