The curled antenna does suggest Pompillidae but I wouldn't rule out Ichneumonidae either.

Hi - Nice picture.

Its an Ichneumon of some kind. There are no UK Pompilid species that look like that and the antennae have way too many segments for a pomp - a pomp would have 12 or 13 segments depending on the sex. pic. Probably the best person to give you a hint as to species would be Mark Shaw at Edinburgh Museum - hes an expert on parasitica.

Thanks for tip - I found his e mail address and have sent him three images. If he has the time to reply I will let you know his conclusion.

Well I cant tell you what it is, but I can give you a good guess on the sex... The curled/long antenna are strong indicators that it is a male.

Then again, the ovipositor sticking out of the rear end rather strongly suggests its a female..........;) . Antenna curling is not really a reliable indicator of sex in Hymenoptera I'm afraid, though some Sphechid males do have the last 1 or 2 antennal segments curled round upon themselves.
