Hymeniptera? id help please

[chrisjohnson]

This insect was photographed in June last year on the island of Eriskay in the Outer Hebrides.
I'd appreciate help with a possible identification. I appreciate that id from photographs is difficult but a guide to family or genus would help, so if I see it again I can attempt an id.






many thanks

Hi Christine,

It is Hymenoptera, and I think in the family Ichneumonidae. Check out this site where you can find wing venation of many of the families, although it's in Catalan there is an English translation (at the top right) if required.


There is a forum for wasp ID on HYMIS you could try and might be lucky.

Thank you Janet
We suspected that it might possibly be an Ichneumon. If so it's a job for the experts and without a specimen it will probably remain unidentified.
However I'll try the HymIS forum, I might be lucky and get an genus.

Evening Christine,

Yes, Ichneumonidae is correct. Note the two-part hind trochanters, and two cross-veins with a horse head-like wing cell (though certain wing veins of couple of sub-groups don't have this feature due to cross-vein placement).

As for genera, good luck. These are extremely difficult even with the insect in your hands, as they say! A couple of points look quite obvious here so you may get beyond sub-family, but then again maybe not.

Good luck

Take care,

Jason
