Really nice image...
Just curious, did you photograph this in the water?

Yes - it was in a watchglass in a retort stand over a black background, with one remote flash off to the side, and much trial and error (as always, with me!)

Well worth the effort!
Your image really shows of the "swimming hairs" (which apparently are characteristic of this genus) quite nicely.

Berosus sp.
fringes of setae on middle & hind legs diagnostic
