Hi BubikolRamios
nice, I think 1st is Stonefly nymph (Plecoptera)
About another I'm not sure; BTW, I think 2nd and 3rd are once. and 4th maybe a kind of Acari. Unfortunately I can't say more thing... :)

Hi,
I agree with Sara, that 1st is a stonefly - Plecoptera and 4th is Acari. Then 2nd and 3rd are nymphs of mayflies - Ephemeroptera and the last one is crustacean Copepod
Cyclops or some close genus ;)

Thanks.
Note that the fourth, does look like acari to me too, but note the thing is very fast swimmer, rapidly cahnging directions, and it does not come to surface at all.
Just never thought of any underwatter acari till now.

your acari belongs to the genus Eylais, but species name impossible without a closer study. There are many species of underwater acari (Hydrachnidia). In The Netherlands about 248 species. Your Ephemeroptera is indeed Cloeon, but be carefull with the name C. dipterum, for it may be a complex of species. Some authors believe that there they include C. intextum and C. praetextum, but others don't. On your photo however, I cannot even decide if it perhaps is C. simile, a true species.
