Hydrometra stagnorum
Water-measurer, nymph
This nymph sucks out a midge pupa, that is hanging head down under a a duck weed leaf.
(It is the grey subject where the thin sucking tube of the Water-measurer is in). You can
still see the breathing 'horns' on the midge pupa. Further there is a very tiny,
mite-like animal on the duck weed leaf in front and a Microvelia nymph on the last
duck weed leaf. What the red and brown thing under the Water-measurer is, I don't
know.
