Hi again,

here's another larva I couldn't take a sharp picture of. Is this a chironomid, too? Or something completely different?

Length about 11 mm.

Thanks in andvance,

Not an insect this time, but a worm (Naididae) - possibly Dero

Many thanks, Tony! Finally I've found an aquatic worm... this is even better

I agree with Dero spec. You can even see the forming of a posterior zooid (asexual reproduction).
@ Tony: I didn't know you have experience with oligochaetes.... It is one of my favourite groups
