Hi everybody, my new-years-vow was to keep on finding rare insects and other anuimals :) I think it's quite a good start to find a new dipteran family for me, Ditomyiidae on the second day of 2010 :) It was reared from a polypore. Two specimens so far, one at least is male. Is Ditomyia sure? I will post a pupa also, presumably of this species. Happy new year to everybody!

ocelli present, small head, antennae with 15 segments. fit! Humpackbed thorax, fit! Now the wing venation will tell the possble genus. There are two in Europe. For genus show better the wing to see if there are or no transverse bands... if not, Symmerus. :p
Don't forget the Cremifaniidae :p I hope you find many. ;)

Hi Jorge, I did not forget to collect for You, in spring I'll surely collect Aulaigaster sp, they are always present on a big sicamore tree at my university. Cremifaniidae I can not promise, but who knows :)
Here's the wing:
PS this piece of wood with polypores on it was very useful: the Calcosyrphus larva and seve4ral terrestrial Chironomids and also Ula sp (Pediciidae) larva wasd gfound in it! I think it may be so rich in diptera because the log from which I collected stood directly in a brook, so it was really wet.

you are right. Ditomyia sp. The last photo shows clearly the transversal bands-

Was it reared from that larva determined as Ditomyia fasciata? If so, what about final determination of imago?

No, that was from someone else. I did not see such larvae, only imagos and exuvia.

Sorry to go off topic pwalter, but I am curious as to how and where you raise your dipterans. Do you use an emergence trap, terrarium or something else?
I am considering doing something myself. To other users horror I guess, cluttering the forum with every single find I might have.

Hi, i just collected bigger pieces of rotten wood with fungus on it with leaves. Than I kept it in a sealed ice-cream box for weeks, later I searched the whole mess thoroughly. I picked some intersting larvae. Than I took a piece a fungus, and placed it in a small (3x3x4 cm) sealed plastic box with the larvae. No air holes, but maybe you can make some. I checked it from time to time. Apparently there were larvae in the fungus itself, also, cause I placed different larvae on the fungus. It was at room temperature.
Good luck! Keep the thing wet! When I saw mature flies, I put it in the fridge (8 Celsius) for as day, photographed and separated the flies and put the fungus again to room temp.

Thank you. I will try to make an emergence trap to put a bird's nest in this spring. But might try wood and fungus the manner you described also.
Did you put the whole thing in the fridge or just the adult flies?

The whole box with the fungus and everyting. Just at about 8 Celsius. It did not hurt the still unhatched larvae. Also, I think some species might even need lower-than-roomtempreture circumstances. But Limoniidae and Ditomyiidae like room temperature, as far as i can tell.

If someone has a key it would be great to know the sp. Thanks!

Looks pretty much like Chandler's illustration of
D. fasciata.

I'll rephrase that: Hutson et al illustration...

If you still need confirmation, this is certainly
D. fasciata :)
