Hi,
I’ve found this species on highbush blueberry plants in late May.

I'd say Sciaridae rather than Cecidomyiidae...

Thank you!
...and the fellow above is also from Sciaridae?

No, it has two pairs of wings, so not Diptera and from a better angle you'll note the constricted waist - so will be Hymenoptera.
As to general and useful aestherics, you may also appreciate there are more antennal segments too.
Still, both Sciaridae and Cecidomyiidae are alike in that they are Nematocerans, which have far more antennal segments than Brachycerans (just 3!), so mis-identifications happen. It just shows you're branching-out!

I see now, that I was in a big mistake!
I thought all of them are pests of my blueberry plants - gall midges. but none of theme are this species.
I've got two more species, that I firstly though, they may be gall midges, as I see now one for sure is not.

But this one seems to be Dasineura

The insect in post #6 is another wasp species. The one pictured in #7 is a fly - I'll let someone else comment on that one.
Look at the constriction between the thorax and abdomen in post #6. Compare that with #7, in which the thorax leads almost straight into the abdomen.

The second image appreas to be a Braconidae, the third is Cynipoidea, probably Figitidae. Now you can see why we need to have separate threads for unrelated images, as these two belong in a different forum on this site. ;)
