Epeorus dulcianas?

Hi, Roger. Long time no chat.

I think I’ve nailed this bug to Epeorus. It was photographed yesterday on a central cascades stream that I cannot publicly name. The hatch started around 11 am and was going strong when we left mid-Afternoon. They were hatching from fast, clean, cold (48F) water running over gravel.

The bodies were about a 17-18 hook size, which got me thinking dulcianas based on what I read on troutnut.

What do you think?

Hi Jim-

I am not seeing anything that would rule out Epeorus. How did you come to suspect it may be Epeorus dulciana? I am unable to find any mention of that (somewhat obscure) species on Troutnut.

The body length was about 5mm, maybe a hair bigger. I’m pretty good at eyeballing a specimen on the stream and coming up with the standard dry fly hook size. These bugs were 18, maybe approaching 17, definitely not 16. A TMC 900 in size 18 is exactly 5 mm.

According to what I read, dulcianas is the smallest species and 5-6 mm is in that ballpark.

Hi Jim,

All I can say is that yours looks pretty similar to mine, although the color's a bit more vivid (maybe due to being photographed more freshly after emergence). I still don't have any updates on whether the one I photographed is dulciana or anything else.

Whatever the case, it’s sure an awesome little bug!

Thanks for the reply. Good to hear from you!
