Hi Mark, Based on this snippet from the scientific paper by M. D. MEYER AND W. P. MCCAFFERTY, Nixe kennedyi has been identified in the Russian River. "Nixe kennedyi (McDunnough) Previous data.—McDunnough (1924): NAPA (Calistoga); Mayo (1952b): AMADOR (Amador Cr, Dry Cr); Day (1956): ALAMEDA...

Congratulations on your 1 year anniversary. I most sincerely appreciate your fantastic work.

Hi Kado- The Olympia version is called the Deschutes River, not the Little Deschutes River. Howsomever, a tributary of it (called the Little Deschutes River) does flow into the main stem of the Deschutes River several miles SE of Deschutes Falls Park on the Bald Hill Road SE. Deschutes River...

Hi Tom- I believe it to be a Crane Fly larva, possibly (but not necessarily) of genus Antocha.

Hi Billy- I believe this female imago to be Callibaetis ferrugineus hageni.

Hi Mark- Please see above image of the extended ninth abdominal segment in question vs an image of ninth segment of a Drunella grandis female subimago from Troutnut.com.

Unlike any other North American Ephemerellids, the ninth abdominal segment of Eurylophella species are about twice as long their ninth abdominal segment.

Hi James- You got the family (Ephemerellidae) right, but rather than being of genus Drunella, I believe this female subimago to be of genus Eurylophella. Did it come from WA? If so, it is probably Eurylophella lodi, the only Eurylophella species which has been reported (in a scientific paper)...

Thanks, Mark. I am interested in any scientific paper containing information that can be used to supplement my Mayflies of N. America database. And, that paper certainly does. Here is the information that I (now) have on Paracloeodes minutus: Family name: Baetidae Scientific name...

By searching your Baetidae mayfly contributions to BugGuide.

family: Baetidae genus: Paracloeodes species: minutus lifestage: nymph Yes, of course I cheated. :)

Hi Tom- I believe they are freshwater snails of family Planorbidae (Wheel Snails).

Hi SculpinSwinger- I believe your Manitoba female adult dragonfly to be a Rusty Snaketail (Ophiogomphus rupinsulensis).

Hi Gary- I believe it to be a female Shadow Darner (Aeshna umbrosa).

Okay. Your posted images were immediately recognized as being a damselfly nymph, which yielded order, suborder and lifestage. The primary visual clues to family were antennae, legs, caudal lamellae, and overall body shape. However, then things got decidedly more difficult, as the vast majority...

Hi Mark- My SWAG is: Order: Odonata (Dragonflies and Damselflies) Suborder: Zygoptera (Damselflies) Family Coenagrionidae (Narrow-winged Damselflies) Genus Argia (Dancers) Lifestage: Nymph

Hi ABITNF- I believe this male imago to be Leptophlebia nebulosa.

Sounds like you weren't born with webbed feet (i.e. in Western WA), so there is no practical remedy. ;)

Present, although somewhat late to the party ;) My guess is that those roundish things in the vial might be Seed Shrimp. And, I certainly agree with those who suggested leeches and mosquito larvae.
