Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

Caddisfly Genus Ceratopsyche (Spotted Sedges)
This genus has been proposed off and on for years. For reasons beyond the scope of this hatch page to explain, it briefly had most of the important species of the most important genus Hydropsyche in its fold. They have all been moved back and the name Ceratopsyche is no longer valid.

Jason: What species', in common angler language, are represented in this genus? I'm trying to determine which ones I should spend my time on imitating them. Are they October Caddis, Grannom Caddis, etc. Are those afore mentioned sedges? I would like to know the names so I can tie them the correct size and colors. Just trying to learn. Thanks
