These tiny Baetids have been on the menu latelty. Sorry for the crappy photo hard to tell if the hind wing is even there. I think it is. less than 5mm long. Any thoughts?

Hi Eric-

Any thoughts?


My guess would be Plauditus punctiventris. I believe hind wings are absent in your photo, and that what appears to be hind wing slightly protruding behind the left fore wing, may actually be a joint of the right hind leg.

Eric- It's grasping at straws, but maybe Acentrella? I can't tell if it's just the angle of the photo but it looks like there may be a small "knob" on the top of the mesonotum.

Thanks gentlemen, I know it's a terrible photo. the little bugger flew away before I could pickle her. Tempermental models, they are all so flakey. ;)

I'll have to see if I can get a few more. At least I know the color and size for my immitations. and it's been very nice out..

Now you're speaking my language.
Oh, and I know that spot...

I think it is a size 22 TMC 2488 like this...

or maybe this...

or maybe even a TMC100 size 22 like this...

All men who fish may in turn be divided into two parts: those who fish for trout and those who don't. Trout fishermen are a race apart: they are a dedicated crew- indolent, improvident, and quietly mad.

I like those. especially the top one. Nice long abdomen.

Looks like a tiny Sulfur to me (now that sounds vaguely familiar). ;) Perhaps Procloeon?

I don't like the road I'm about to venture down but, how much interspecific color variation do you think is present? The reason I ask is because there are a bunch of olive colored baetids around too, basically the same size. Both males and females have the olive coloration and the golden tan coloration. I know for a fact that the olive ones have hind wings with a costal projection, the forwing intercalaries are in pairs and the costal projection on the hind wing is somewhat broadly based (I don't like that character). the specimen I have is a female, its a brownish olive color 5.5 mm. I suppose we could be talking about separate species emerging simulatiously.

this is what the hindwing looks like please excuse my poor rendition but I think it's pretty accurate.:

Among the Baetid hind wing venations which are illustrated in The Biology Of Mayflies, the venation of your rendition most closely resembles that of Acerpenna pygmaea, which was classified as Baetis pygmaesus at the time the book was written.

thanks Rodger. When I take it through Merritt and Cummins that's where I wind up too. But that still doesn't give us an Id for the Baetid pictured, that's why I was wondering about the interspecific variation in color, that always dubious character...

Eric-

If you are able to capture a female subimago of the coloration and size of the photo you posted, I suspect your ("I suppose we could be talking about separate species emerging simultaneously") statement may be proven to be accurate.

Oh, sorry. I'm a little slow on the uptake sometimes.

I'm with you. I feel the same way about baetid hind wings as well. It's been my experience that it's the rare specimen that matches anything diagramed.

Assuming your diagram is of a male wing and absent further evidence your little olive one is most likely Baetis. Acerpenna has a more acute process and the wing margin beyond is undulate.

Do the little amber ones have double or single intercalaries? Usually when they are this color, size and body shape one of the spur wings is the match. Either Procloeon or Anafroptilum would be my guess. The habitat sure looks right...

Well I've caused enough problems with this thread. I say we table it until I stop paying attention to those rising fish and get some of the little critters and take some decent photos. ;)

So tabled...You trouble maker! :)

Lovely autumnal photo there! There never seems to be a bad day to be standing in or next to some moving water.
