Chimarra aterrima is the most important species.  

Where & When

Time Of Year (?): Early May to mid-June

The pupae emerge by crawling out onto land.

Hatching Behavior

Time Of Day (?): Morning to midday

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

Time Of Day: Afternoon

Chimarra females dive to the bottom to oviposit.

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? Lafontaine emerger in what color?

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.

Does the pupa retain the orange color of the larva or do they have the color of the adult?

i recently came across with a bright green one of these. Is that the same or a completely different species?
