Hello!

Birgit Gabriel asked me to post these photos here of a larva (size about 25 mm) she found in a dead oak near Berlin/Germany on May-19, 2007.
I could not really help her, but I vaguely thought it could perhaps be some Tipulid larva (of the wood breeding species) (??).


[EDIT: Title changed from "Diptera larva?" to "Diptera pupa?"]

hi Jurgen,

this is already a nymph.
probably is more or less close to this:

anyway looks interesting, try to keep that one and see what emerge (or your friend keep that).

Ah, yes. Now that you state it... I had Xylophagids in mind, but I only thought of the larvae, which look quite different. So I had ruled that out...

The pics are of last May... Wink

This one is a male pupa of crane fly in the genus either Ctenophora or Tanyptera. The large, broadly flattened, deeply crenulated margin of the breathing horns are a important character to recognize pupae of this group of crane fly.

Many thanks! At long last the solution of this miracle... Grin
