Can anyone identify this large black wasp?

Hi,

 

My sister's boyfriend found this large wasp a few years ago in Kent - apparently it was quite aggressive. I've shown it next to a common wasp and hornet for a size comparison - does anyone know what species it is?

 

Thanks!

    It is a scoliid wasp, http://en.wikipedia.org/wiki/Scoliidae, but from what I can tell they are not indigenous to the British Isles. So, either this one was imported from, for example, France or it migrated in from the South, perhaps after strong winds. Worthwhile to get this specimenexamined and properly recorded by a British aculeate specialist. It might be Megascolia maculata.

      As Paul says this is a Megascolia species and not a UK native. It most likely hitched a ride on some commodity, though I am not aware that this is frequent event. This is a southern European species and I am confident it will not establish itself in the UK as the females provision their solitary nests with the larvae of the European Rhinoceros beetle, Oryctes nasicornis, which itself has a southern European distribution. A super find though and an interesting record - if you send details (where, when and by who it was found) to sjh@nhm.ac.uk I will pass on to the Bees, Wasps and Ants Recording Scheme.
