I opened a new Tipula obscuriventris larva standing in the same sample






This larvae was shorter (about 40 mm length)
and I found another Diptera lava attached to tracheal trunks of Tipulida at the level of Abdomen Semgent II

This larvae seemed to me to be wrapped by some organic "bag" well ornamented by tracheas





the wrapping bag is a little bit yellow colored
with a chitinous black point where the Tachinid (?) larva sticks to the tracheal trunk of Tipula

On the transparent segments of the endoparasitoid can be seen rows of dark spicules
This larvae seemed to me to be older than the others larvae founded in the first observation

Same cephalic skeleton and a little piece of dark material found in each of all those larvae:
is it the tool used to puncture the Tipula trachea ?

merci pour l'attention

the Tipula larvae opened and the (Tachinid) endoparasit visible









The larva parasitoid is wrapped in a organic cuticule



aspect of the spicules raws on the abdominal segments
