Hello, I found this larva in the calyx of a rosmarinus flower, on the bush on which I often see Oxiaciura tibialis (see http://www.diptera.info/forum)./viewthread.php?forum_id=5&thread_id=24100 This larva is eaten by a very small ectoparasitoid Toryminae larva (the little white "tooth" at the bottom left). So I didn't get any blue pupa of Oxyaciura. Does this big larva (ca. 2-3 mm) look like an Oxyaciura larva?

The parasitoid emerged and I get to Torymoides kiesenwetteri (but I"m not a specialist at all).

It looks like a chalcid parasitoid wasp larva, not necessarily a torymid (which can be also a hyperparasitoid!); other possible options are Pteromalidae and Eurytomidae. Every data in this line and observations you can do, might be new and deserving a good publication!

What about the host? Does it look like Oxyaciura larva? I have no doubt about Torymidae and I'm quite sure of the genus. HDumas attached the following image:  [67.6Kb] Edited by HDumas on 11-12-2011 23:23 Greetings from Provence |

The larva on the picture is certainly a wasp larva (either a Eurytomidae, or Pteromalidae, or Torymidae). The two first are parasitoids (no records, but some could be on Oxyaciura); torymids are either parasitoids, hyperparasitoids (on Eurytomidae, etc.) OR SEED-EATING PHYTOPHAGS

I understood you first answer during the night... so it's clear for me now. Many thanks Valery, and sorry for my slow brain. Greetings from Provence |
