4.14.07 Mayfly ID

Super Pupa
Can anyone ID this insect for me? I didn't see any tails on this fly, but it looks like a mayfly.

It's really hard to tell.

It looks like it has two sets of full sized wings. Look closely. I see no hind wing that you would normally see on a mayfly (exception, pseodocloen). I've never seen one like this.

How big was it? It looks like there are two sets of the same size wings - look at the thorax there are two places where the wings connect. The wings also curve inward in the middle of the back edge...........and the head does not look like a mayfly - it has antennae. Probably not a mayfly.....

The fly was about a #14. I tried to ID it, but couldn't find any pics of a mayfly that looks like this one.

Looks like the general shape of a mayfly but, Matt, like you said, the head doesn't look like a mayfly, it looks like a little stonefly head.

Did you say you took that photo at the Ken Lockwood Gallapogos?

Yellow stonefly......... Perlodidae............
maybe isoperla (yellow sallie)

Thanks....I did see small stonefly nymph shucks on the rocks, but they looked small...but there were small black stoneflies around too.

What's the deal with the wings though? Don't stoneflies have wings that lay flush against the body?

1. Yes that is normally true. That left extension may actually be part of the lower(underneath wing); giving an optical illusion!
2. Not all insects are perfect.
3. Head, antenna, thorax indicate a 'stone'.
IMHO.......

* its always best to take more than one photo.... :dizzy:
** thanks for the photo! :)

I agree but, the wings don't indicate stonefly at all. Take a look at stonefly wings, they are heavily veined. These wings are a flat color. The cross veins in these wings are like a mayflies. The head on the other hand...
 
Shape seems off for a stone to me. Thinking a little out of the box, how about an early alderfly? They have smoothe clear wings, antennea and a stonefly-like head.
 
Looks like a adult Ear wig, found under tree bark and rotting leaves..I need a better pic to be sure...
 
I just heard back from Thomas Ames, one of the Easts' fly fishing bug experts.

He said it is a freshly hatched stonefly...probably a little yellow or little sepia. The wings will harden and shrink to fit nicely over the abdomen of the fly. He said they do this in about an hour. Unless you see them right after hatching, you will miss this brief stage.

In all the years I have seen stoneflies, I have never seen them in this state. I guess I should have gone with my first instinct. We never stop learning in this life, do we?

Thanks Steve. :applaudit

Matt ><)))))'>
 
Matt,
Thank you for the follow-up!
Sometimes after a few good photos, there still may be questions about an idenity!

* I need a digital camera.............. :dizzy:

Qg.
 
sstasiak-

That is definitely a stonefly. The prothorax and hind wing shape leave no doubt. My guess based on size, color, and April presence in NJ would be a Least Sallfly (Haploperla brevis).
