help with 2 mayfly larva

Recommended Posts

Hey everyone, today was my first shot at stream side insect collection, it turned out great. I got several different sizes of scuds which I did not even know we had here, plus some nice louse and of course mayfly larva, I have no idea what they are i know they are rock clinging mayfly larva but can anyone identify these? they may both be the same type. I also have several which are a lot smaller but i did not photograph them, if anyone is interested though i would be more than happy to photograph them. From the little research i have done it looks like these 2 may belong to Genus Ephemerellidae?

that would be my guess as well, we do have awsome march brown hatches around here and in the same area i pulled these guys from, In regards to the post about it being a green drake i dont think so as there nymphs seem to be very long, these guys are stout with thick legs. And yeah i did give trout nut a look i did that before i posted here hehehe.

a quick look on google image for march brown nymphs reveals it most likely is the suspect, thanks Johny!

Hi Druce-

 

You are right about them being rock clinger mayfly larvae, but you got the family name wrong. Rather that being Ephemerellidae (crawler mayflies), they are Heptageniidae (clinger mayflies). If I am able to identify them to genus, or genus and species, which will take longer, I will let you know.

 

EDIT: I believe your 1st photo to be Stenacron interpunctatum (see bottom center image), which fly fishers generally refer to as a Pale Gray Fox among other names.

 

EDIT: I believe your 2nd photo to be Stenonema femoratum, which fly fishers generally refer to as a Light Cahill or Cream Cahill.

This all ends up being conjecture if the region is not known. East coast and west coast bugs differ greatly even among similar genus, family and so on.

Dead language? LOL that's why it's still used universally throughout the world, and many "live" languages are heavily based on it... ?

It's a dead language because no one actually speak-speaks it. Like we speak english, or how most the germans speak german, there is no, "Oh yea, he doesn't speak english, he speaks latin." (That I know of)
