Posts: 5	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?

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.

Site Editor "Bear Swamp," PA Posts: 1636	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.
