Female Dicosmoecus gilvipes (October Caddis) Caddisfly AdultFemale Dicosmoecus gilvipes (October Caddis) Caddisfly Adult View 16 PicturesI've been hoping to add a really good October Caddis to the photo collection here for years, but so far I had struck out on finding them on the river. Tonight, this one flew into the kitchen during a pizza party at a house along the river, and was quickly pointed out -- one of the perks of hanging out with other aquatic biologists! Maybe next year I can finally get a salmonfly on taco night or something.

Anafroptilum conturbatum (Tiny Sulphur Dun) Mayfly NymphAnafroptilum conturbatum (Tiny Sulphur Dun) Mayfly Nymph View 2 PicturesA moderately rare mayfly perhaps because the nymphs are fragile that nymphs are usually damaged in collection making identification more difficult.

Male Ephemerella aurivillii Mayfly DunMale Ephemerella aurivillii Mayfly Dun View 7 PicturesThis dun was collected in proximity to this spinner, and to this female that looks like the same species.

Among western species, it most closely resembles Ephemerella aurivillii, of which I reared a specimen from a positively-identified nymph and photographed the male dun previously in Alaska. In the photos, this dun does not seem to have the same evidence of the nymph's dorsal (Dorsal: Top.) stripe, but that's due to the lighting. A faint stripe is apparent under the microscope, as it is in the female linked above.

They do appear to be a bit short for aurivillii, with the male at 8 mm and the female at 9 mm, but the spinners could be a bit longer.

Among the other Ephemerella mayflies documented in Montana, Ephemerella alleni and Ephemerella mucronata are the only two others that seem to not be ruled out.
