Hi folks,
The standard of pictures for entomological purposes for this site is outstanding
Alas, I must now sully it with this effort, for which I hope it will serve a purpose.
Anyway, I accidentally bought a fine mesh net today, and somehow found myself sifting a local river

These little chaps were fairly ubiquitous (and nowt else really). I believe it to be Ephemeroptera Baetis - but can you tell what 'shade and shape' it will turn out to be?
BTW it was tiny - no more than about 2 opr 3mm - what would be a typical small spate river size for this beastie be when it surfaces?
