Caddisflies
Some anglers consider caddisflies to be even more important than mayflies, and on many rivers they're right. Angler-entomologists focus less energy on them because they are slightly less prone to cause a feeding frenzy among the trout. While that does happen, they are more commonly an intermittent food source during the times when it seems like nothing's hatching. Understanding their life cycle is of paramount importance to any fly fisher, but learning their quirks species-by-species is less useful than with mayflies.
This common name refers to only one order.
These are pretty much always called Caddisflies.
Some say caddisflies are even more important than mayflies, and they are probably right. The angling world has taken a while to come to terms with this blasphemy. Caddis imitations are close to receiving their fare share of time on the end of the tippet, but too many anglers still assume all caddisflies are pretty much the same.
Caddis species actually provide as much incentive to learn their specifics as the mayflies do. There is just as much variety in their emergence and egg-laying behaviors, and as many patterns and techniques are needed to match them. Anglers are hampered only by the relative lack of information about caddisfly behavior and identification.
Rhyacophila (Green Sedges) Caddisfly Pupa
View 11 PicturesI collected this pupa and several like it from the same stream and on the same day as this larva. I suspect they're the same species. Every pupa I collected was in a brown casing like the one shown in one of the pictures below. I cut this pupa out of its case after a picture so you can see more details. It is close to but not fully developed.Collected
