hi ohter insectforum, I found a parasitaric larvae (wasp) on Araniella spec. Next to this spider, I found some kind of Ichneumonidae sp. Is there a connection between larvae and wasp? or just accidental? What kind of wasp are these? (the imago) This wasp got a clear pterostigma and the foreside of the wing got many hairs.

Your pics recall the parasitized spider of my thread http://www.dipter...d_id=15117. Chris suggested tribe Polysphinctini of Ephialtinae (= Pimplinae) of Ichneumonidae. I really wonder whether your imago might belong to this tribe. Regards, Sundew |

No, not Ichneumonidae. These are Tenthredinidae and most likely Nematinae. Further ID is not possible from photos, I'm afraid.

The Tenthredinidae sp. (pic2) was about 5-6mm Today I collected another ecto-spider, I'll try to let it grow The larvae (wasp) on Araniella spec. Edited by Robert Heemskerk on 25-01-2009 22:47 Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

I find a resemblance with Braconidae to him, especially the antennas and the wing nervation with this large stigma! In more the head is very triangular and not transverse

Thank you cthirion, for your comment. I'll call it Braconidae Hereby, one lateral close-up from the head Edited by Robert Heemskerk on 26-01-2009 17:38 Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

The wings of Nematinae on various photographs have a less lengthened, more flexible form and the more transverse head in the absence of being able to see other characters here!

I totally agree with Cthirion, this wasp should belong to the family Braconidae. If I had to guess I would say subfamily Braconinae. But you probably won't ask me to guess .

Hello, Sorry to be boring. But does somebody have a reference for such exo-paratitic worms on a spider (if I may call them this name) ? Pierre Duhem |
