My guess and it's only a guess would be Maccaffertium. When were they collected, what size were they and where were they collected?

Posts: 10I collected these today on the Big Flatbrook in Sussex County Nj. I would say going by hook size probably 12-14. Not sure what a Maccaffertium is..sorry new at learning all these aquatic insects. Please advise if you could? Thanks for reaching out!

Maccaffertium is the name of a heptageniidae (flat-headed) mayfly nymph and adult. The reason I guessed Maccaffertium is because the front leg is fairly wide at the femur and looks to be banded with brown and a whitish color and because it has the general body configuration of a flat-headed nymph. I'm going on guess work as much as anything.

Maccaffertium


I thought this was the nymph of the March Brown. BTW Big Flatbrook was my "home" trout stream for about 25 years until I bought a cabin on the Delaware River.
