Time Of Year (?):The pupae emerge by crawling out onto land.Hatching Behavior
Early May to mid-June
Time Of Day (?):There are conflicting accounts of the egg-laying behavior of this genus. Gary LaFontaine writes in Caddisflies that they serenely ride the surface in great numbers to oviposit. In Selective Trout, Swisher and Richards say they dive underwater. Their mention is less detailed and I'm inclined to believe LaFontaine, but perhaps some species exhibits each behavior.Egg-Laying Behavior

I would like to see a picture of an emerging Chimarra or a pupa stage before emerging if anyone has one. I am baffled and curious to how and when they change from a yellow/orange larva to a black adult fly. Also, what would be a good emerger pattern for this fly?

Seems like dead drifting the pupa pattern during the emergence time is a good way to fish this before the adults are on the water.Replybright green? 1 Reply »
Does the pupa retain the orange color of the larva or do they have the color of the adult?
