Hi Diptera fellows

I propose some view of Hemerodromiinae larvae, I suppose they are Hemerodroma Meigen ?
These organims were collected alive in the freshwater of a Haute Ardenne belgian fount "La Lienne"
The water was terribly ferruginous and few water fleas that live there were literally covered by a "red orange sticks" (which I think is goethite and limonite).

Hemerodromia larvae (3 mm length) were not covered by these precipitates.

But they have a strange appearance. Is the natural appearance of their skin?

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
