Hey dipterists

In a low stream river, amid deciduous trees, embryo masses
the sample is still alive . There was a few Tipulidae, Empididae and some Chironomids

Could they be Diptera embryo ? Nematocera?
They have, capsul head, "eyes" spots and seem to have "hooks" or crochets
I put here a few pictures
Thanks for the attention

The egg mass is reminiscent of some Ceratopogonidae.

If this is ceratopogonidae then it must be dasyhelea

Do you mean that dasyhelea egg clutches are similar to those of Dixa nebulosa ?

No. I'm not saying this. If the larva hatch and they appear to be ceratopogonidae, than this would be dasyhelea. I have no experience with eggs, except but my girlfriend😊

The larvae are not Ceratopogonidae, they are Dixidae. Other pictures here - http://www.dipter...d_id=69878

in the sixth and seventh photo I can clearly see hooks, which Dixidae larvae do not have in their anal segment.

Dasyhelea eggs are distinctive, bent into a semicircle, unlike the photo here showing a bent larva within a convex egg.

Surely the hooks in the photos are on the prolegs on abdominal segments 1 & 2? Typical Dixidae.
