Posts: 1Hello Jason - this is a fabulous site. Are you from Ithaca!

Anyway, I've been finding what I think are small mayfly larvae in a stream near here. How small can mayfly larvae get? And do they emerge in singles? The trout and shiners are sipping something fairly regularly.

I have a little 6 1/2 foot 3 weight, and I'm thinking of trying to find a nymph or fly that would be an imitation of these.

Hi Spatsizi,

Yeah, I'm in Ithaca! I finished Cornell in January and I'm sticking around for a while before heading to grad school in Alaska next summer.

Mayfly larvae (nymphs, actually) can get just about microscopic, because they may have just hatched from the tiny egg, especially at this time of year. But if you're seeing trout sip something on the surface at this time of year, it's probably not mayfly nymphs, unless they're full-grown nymphs of a tiny mayfly species just about to emerge (2-4mm Tricorythodes mayflies might be around).

Which stream, and have you seen adult insects on the water when the trout are sipping? At this time of year the most likely culprit for that sort of thing would probably be flying ants. It sounds like you might need a dry fly instead of a nymph.
