I believe this may be the dun from my previous post, but would like some clarification. The netting that you see is actually from my landing net.the spacing across three holes in the landing net is 11.74mm. not sure if the first pic is fully emerged

thanks for your help

Hi Fred,

Yes, I believe it to be a Callibaetis female subimago, but would sure be a lot more comfortable making that call if I could see its hind wing. :-)
Best regards,

Hi Fred,

Now that is the way Callibaetis (Speckled Duns) usually look. Fairly confident it is C. ferrugineus hageni. The clear wings on your earlier topic's specimen made me cautious but I have no doubts about this one. Is it the same species? Most likely, as the male spinners can have clear wings without the blotches normally associated with this genus. Its nymphs are very good swimmers and actively dart around in the weeds prior to and during hatching. They are a favorite trout food and by far our most important western stillwater mayfly.
