I have these photos from the insect that used to be living on the pool/pond.

At one point,there were up to 14 in there,now I see none(as I now believe they have molted and gone from water living to air)

Any identification is most welcome.

A bit fuzzy I know,but as you can see,the insect crawled out of it's shell through the middle of the back.(pic#3)

Fuzzy indeed. The general body structure is ant-like but I don't know of that many aquatic ants.

Maybe a wasp of some type?

It was on my cell phone..

Anyway, it scooted across the water for many weeks,they didn't seem to be bothered by other insects in the water,the polliwog didn't seem interested in them either.

And what wasp would live under the water for 2 months then molt into an outdoor air breathing insect?

We just don't know.

Possibly a water skipper, then, although the shell looks a little thin-bodied.

New skin try-outs...

I will be further specific... it scooted IN the water,not ON the water,they all lived below the surface for the last month(s),now all have molted and left just this shell,only in the last few days.

That very could well be!Thanks.

Dragonflies are predaceous as both adults and nymphs. The nymphs are fully aquatic and able to beathe underwater. Funny that you note that other insects and the polliwogs did not associate with the nymphs, as I suspect that they did not want to become dinner.

Funny you should say dinner.. My brother just came for a visit and he also said nymphs, he has them in his pond and is able to quickly identify them.

He has said the larger adults have dined on small fish much less polliwogs.

Again,thank you!
