Hello! Are you able to identify everything - I am impressed. Could you even tell me anything about this animal? It came out of beechlogs when brought in the warm room this march and is about 1cm long. I've more pictures if you need, a ventral view for ex. Thank you for helping Maja dipdip attached the following image:  [61.75Kb] |

Hello Again I have lots of these beautyfull animals in my living-room. Here I've a wing and a lateral view. May be I should tell you that there are lots of Phymatodes testaceus (and Pogonocherus hispidulus) coming out of the Wood too. And there is a other one... regards Maja Beutler dipdip attached the following image:  [59.24Kb] |

Looks like a few species of braconid wasp - but dead-wood is a difficult substrate because there are so many possible hosts associated with it. The obvious ones are wood-boring Symphyta but also wood-boring beetles and even just invertebrates that overwinter under the bark, like spiders etc. The species with longer ovipositors are more likely to have come from hosts burried deep in the wood, while the others might have attacked hosts nearer to bark level. Nice photos though  |

Chris Raper wrote: The species with longer ovipositors are more likely to have come from hosts burried deep in the wood, ) And here we have lots of Phymatodes testaceus and lots of the first big wasp ... I just hoped that would make the choice between the tenthousends of possible species a bit smaller ... Thank you very much for your explinations Maja |

Yes, likewise - I would love to be able to identify more precisely.  The difficulty is that even quite large groups (ie. subfamilies) are distinguished using very tiny features, such as the shape and length of fine grooves and ridges on the thorax or abdomen, which are not clear enough on photos. It would take an expert who had worked in the field of braconid wasps to be able to say more precisely which sub-family, tribe or genus these belong to.  |

Hi, I asked Kees van Achterberg (certainly a specialist in Braconidae) if he could say anything more about the species. He wrote: The small one is a Spathius (probably S. rubidus (Rossi)); the other one a Helcon. So both are indeed Braconidae. Spathius belongs to the subfamily Doryctinae and Helcon to the subfamily Helconinae. On the internet I found that Spathius rubidus has been reported as a parasite Anobium beetles (Anobiidae).

Wow, thats nice I already lost hope and now I enjoy your answering very much. Some of the beautys are still members of my household. And names are steps to more knowlege. Ptilinus pectiniformis (Anobiidae) was here, too. Have a nice weekend and thank you very much! Maja |
