Thread subject: Diptera.info :: Larvae & pupae - Bibionidae?? => No: Forcipomyia

Howdy,

Today I found various groups of these (or very similar) groups of larvae and pupae under bark of dead trees. At least one Pine, but I suspect also some decidious trees. Length of larvae around 8mm, pupae maybe 4-5.

Best I can find in similarity is in the Bibiomorpha and the shape of the pupae seems to fit that also, but I can't find any exact matches, except for this image by Stanislav Krejcik, where he also takes a (wild?) swing at Bibionidae.

It must be something very, VERY common, so I'm probably just looking in the wrong places ....

Any pointers very welcome!

Thanks in advance,
Arp

P.S. Sorry - forgot: 2021-03-23, Miggelenberg near Hoenderlo, Veluwe, Netherlands.

Come to think of it ...
Any point in letting these hatch to get a proper ID through the resulting imagos, or is that a long shot? Any keys available without spending hundreds of $€$ ?

If it is too complicated for an amateur, I will put them back ...

Cheers, Arp

Yes, worth rearing some adults. I have Boorman's keys (mostly for the British fauna), but there are some specialists who may be able to help further. Forcipomyia is a large genus, but there are a few distinctive species, though the rest require slide mounting for species ID.

Okay, I'll see what gives ... will report back here with any results.

Thanks again Tony!
