I was out today so i had a good look on the river bed when the fishing was slow and i found these little nymphs.

Can anyone help on their names and what they will turn into please

Just anther question if i may

Can the colours vary in different rivers and bottoms?

I'm not the best with the nymphs

Thanks

I can't see enough of No.1 to give any opinion - it would help to see more of the top view (as in No.2).

Based on the shape and dimensions of the prothorax (the first segment behind the head), I'm fairly sure No.2 is Ecdyonurus dispar and will hatch into an Autumn Dun

I'm certain that No.3 is Serratella ignita (formerly Ephemerella ignita) - the Blue Wing Olive.

Colour of the nymphs can vary and my observations of Ecdyonurus nymphs is that they can be anything from dark brown (almost black) through to sandstone red.

Hope that helps

Thanks very much again. Here is the photo you were after. Its not the best but should be fine for you to see what it is
Thanks again

Sorry, but there's still not enough detail in the prothorax to decide if there are backward projections and their dimensions. So I cannot be sure.

If I were to guess I'd say it's probably another nymph of Autumn Dun and just a colour variant
