Used to run into them fishing Big Hunting Creek in Maryland back in the 90’s; mostly the duns, #16-18 (western ones smaller?), not the spinners like the pic you posted. Never hit a heavy hatch but the fish seemed to like them; think I used a grey bodied Hairwing Dun.

Those are his penes...his sex organs for reproduction.Does the pictured spinner have a malformed third (middle) tail? What’s that little loop thing there?
Thanks! But—Now I feel slightly embarrassed for scoping the li’l dudes genitalia.Those are his penes...his sex organs for reproduction.
Hi Mark-Idaho doesn't list any Anafroptilum species but Washington, Oregon and Montana do.
Yeah, apparently there is. I was going by Idaho's Fish and Game guidebook which says there are none in the state. https://idfg.idaho.gov/species/taxa/2011420Hi Mark-
I believe there is actually at least one Anafroptilum species present in Idaho. Please see Anafroptilum bifurcatum.
Thanks for the heads up, Mark. My distribution maps for both Anafroptilum bifurcatum and Anafroptilum conturbatum have now been updated.Incidently, your map shows none in Montana. Aparently they have two species of Anafroptilum.
