Mayfly Genus Caenis (Angler's Curses)
When the important hatches of Tricorythodes were first discovered by anglers, Caenis was given the credit. We now know that the Caenis mayflies are a different group, smaller and less common in trout streams, and they hatch in the evening instead of the morning.
They very rarely elicit selective feeding, but when they do they're very tough to match because they're often much smaller than size 28. This difficulty has earned them the nickname "Angler's Curse."

9 Nymphs
I confirmed the identity of this nymph by looking at it under a microscope to be certain of the shape of its gills and head.
This interesting little Caenis nymph is way darker than any of the others I collected in January 2004, probably a different species. It also has shorter tails.

This is probably the most common lake mayfly in western Montana. It can be found with one or more species of Caenis.
