Posts: 5I 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?

Hi,

I'm no expert on Chimarra, and hope one of the caddis guys will give you a good answer. We have several but they haven't been on recently (perhaps they're out collecting caddis larvae). I'd guess that a black Lafontaine would work, but it's just a guess. I've had my best luck with a CDC adult for this caddis, black body and wing.

Helgie,

Concentrations of little black caddisflies that are seen emerging on the surface are probably not Chimarra. In the information in this section, Jason mentions that the pupae usually crawl out to emerge. They will even use your waders for that purpose if you stand for any length of time in an active emergence site. (You'll notice the freshly emerged adults accumulating just above the waterline.) Rather than a surface imitation like the LaFontaine emerger, I find that something like a small blackish soft-hackle crawled along the bottom usually works best.

As for the color, the transformation from larva to pupa is very dramatic in many ways, and caddisfly larvae are often very differently colored than the emerging pupae/adults. See a similar discussion by clicking on the "Pupa color?" thread in the same section.

Thanks, Gonzo, for the clarification. Again you give me some ideas on what to do when I'm trouting, this time, when black caddis are about.

Posts: 5Thanks for all the replies. I'll have to try the Peacock and Starling pattern. I have found that a small size 16 and 18 prince nymph also works well during the hatch.

I would too, so far I haven't come across one.
I once fished a hatch of chimarra cadiss on the lower east branch in 45 degree water.
The pupa popped to the surface in small groups it seemed.the were very buoyant. The pupa pulsed on the surface migrating themselves twards the shore. Some found my waders and split thier shucks out of the water sqirming and wiggling out to adults.
The pupa were irridecent peacock hearl like color with the ribbing like peacock quill.
The trout were feeding heavily on them and I managed to catch 2 very nice browns on a peacock quill pupa recommend by Budge at the Beaverkill Angler. Before the time of the cell phone camera and video I only have memory.
I tried to create such floating pupa with foam not very successful I let it go to fish other hatches.
