Hi All A couple wasps that are driving me to distration. They were both found in Brampton Wood, Cambridgeshire. Could someone please take a look and see if they are possible to ID? Thanks. Gareth |

I give No. 2 a try: male Amblyteles armatorius, Ichneumonidae. Here the species is common and can be met on flowering Umbellifers. It should have two spikes on the propodeum (see https://www.bioim...091.htm?13). No. 1 is also an Ichneumonid, but I do not dare to guess a genus... Regards, Sundew |

Hi Sundew I believe your ID is correct. I have read that the pines on the thorax and the wide yellow stripes split by a narrow black stripe are diagnostic. Whilst I cannot see the spines, the stripes are exactly the same to numberour pictures I have seen. As far as the locale is concerned. This wasp is recorded in neighbouring counties and I am told likely to under-reported. Thanks for your help, Gareth |

Hi Günter Ichneumon bucculentus is not common at all in the UK but I followed your lead and found a number of likely candidates. https://www.gbif.org/species/5030282 I. albiger I. suspiciosus - https://www.bioimages.org.uk/html/Ichneumon_suspiciosus.htm I. extensorius - https://www.bioimages.org.uk/html/Ichneumon_extensorius.htm I. confusor - https://www.bioimages.org.uk/html/Ichneumon_confusor.htm The hind femur and tibia are "highly enlarged" as per https://www.bioimages.org.uk/html/r170684.htm?4 this could indicate I. confusor or I. albiger - It is suggested here that males are indistinguishable - https://www.bioimages.org.uk/html/Ichneumon_albiger-confusor.htm I think I am stuck with Inchneumon sp.  Thanks for your help, Gareth |
