Golden Stone would have been a good guess. However, that common name is used for adults and nymphs of larger Acroneuria, Agnatina, Calineuria, Hesparoperla species. As I recall, Bill Stark assembled a team of Stonefly taxonomists. who proceeded to assign a common name to each species of North...

For purpose of comparison, please see the nymphal photos of Calineuria californica on Troutnut.

Hi Gyrfalcon22- I believe this stonefly nymph to be of family Perlidae, and that its scientific name is Calineuria californica, and that its common name is Western Stone.

Yes, sad indeed. I received an email from his brother informing of Mark's passing.

Where is Dennis Worley (Denwor54) when you need him? ;)

Hi Jason- See that you just joined this website pnwflyfishing.com earlier this month. Hopefully your presence here will spur more entomology related postings on this forum, which have been rather sparse since the unfortunate passing of our good friend, Mark Melton. In any event...

Hopefully, someone will be found to take it over. The shop and Brad trigger many fond memories for me!

Interesting, I assume they some kind of insect ova, but you already knew that. ;)

Recently received the sad and surprising news that Mark Melton has passed on. For those that don't recognize his name, Mark was a fantastically talented macro photographer and identifier of aquatic macroinvertebrates on this website and others. If any suspect me of exaggeration, just take a...

And I've also seen it many years ago on Dry Falls. Incidentally, although most flyfishers probably believe that Callibaetis are the most populous lake-resident mayflies in the USA, Caenis actually are, and by a ratio in excess of 4/1. Please see Lakes Biotic Survey.

Hi Cowlitz Bottomfeeder- It appears (to me) to be a mayfly imago of genus Caenis.

Agreed. :)

It seems to vary depending on the lake sampled. Some of the lakes sampled in both western and eastern WA have Caenis, and some have Callibaetis, and some have both, and some have neither.

Anyway, here are the top 10 with regard to number collected: 7 Caenis 31455 8 Callibaetis 6703 26 Procloeon 832 34 Stenonema (since mostly reclassified as Maccaffertium) 616 18 Eurylophella 342 20 Hexagenia 302 31 Siphlonurus 292 10 Centroptilum (since reclassified as...

Interesting question, but I don't know.

Well, for those of you whose guess was Callibaetis, I must admit that would also have been my guess also, least before 2011. But quite surprisingly, apparently Caenis outnumber Callibaetis at a ratio of more than 4/1 across the US in freshwater lakes and reservoirs. Please forgive my tardy...

During the summer of 2007, biotic sampling was conducted in (1243) lakes across the (48) contiguous states by individual state agencies. The biotic samples were sorted to the lowest practical taxonomic level and counted by the US Environmental Protection Agency (EPA). Among other insect orders...

Hi Buzzy- Mosquito larvae; please see below.

As shown in my WA Aquatic Insect Emergence Chart, Siphlonurus mayflies can be present in both Move and Still waters. However, I believe the greater likelihood would be that they spent their nymphal lifestage in the lake, emerged from it as subimagos, and returned to it as imagos in order to mate.

Hi Tom- I believe your mayfly image to be of genus Siphlonurus. Please see WA Mayfly Description.
