The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.

Male Stictochironomus Midge Adult Pictures

This midge and several like it, including a female I also photographed, hatched from larvae which were living in some fine mud I'm using as substrate in my bug-rearing aquarium.

chironomids-East versus West

Spring can't arrive soon enough...after ice-out streamer fishing and before the high water levels on moving water venues become more reasonable, I love to fish chironomid imitations in ponds. In ponds containing few forage fish, this begins before the ice goes out entirely. My question is simple: why are chironomid species in the East so much smaller than out West? I have fished the Kamloops area of BC which is, of course, world renown for huge (size and quantity)chironomid hatches and the difference is unbelievable. I suspect it has to do with lack of fertility in my home waters, still or otherwise. Can anyone help?

I returned from a weekend out of town to find that several midges had emerged from my bug-rearing aquarium. I never specifically put them in it in the first place; apparently, they were embedded in the river silt I used as the substrate for part of it.

I'm pretty sure this one and the other specimen belong to the same species, and I'm guessing the variation in antennae form is a gender difference. It's kinda neat. The antennae on the male seem to be made to be imitated with CDC, except that they're about 100 times too small.

In fact, from the ruler picture, you can see that the whole body of this midge is thinner than a size 18 dry fly hook. I'm not sure how a griffith's gnat is supposed to imitate such a thing.
