Malcolm Brownsword sent me the following photos of a ichneumon (braconid?) that was seen visiting orchids on Porton Down, southern England, last weekend. As you can see, it has pollinia attached to the face so he is very interested to learn more about it. I have told him that the likelihood of an identification is fairly remote but I thought I'd offer it up anyway, just in case :)

Many thanks for trying - I thought it would be impossible even to genus :D

Could it be Tiphiidae?

We only have 2 tiphiids in the UK and they are both very hairy and don't really look like this one ... but it is a good idea because they are very common at flowers :)

Which Orchid is visited? (I collect information about Orchid pollinators.) And what is the wasp looking for? Is nectar offered? Many Orchids deceive their visitors and offer nothing. Sexual deception, however, is obviously not taking place here. So what makes the wasp poke its head to the pollinia? It gathered such a lot - will it place them correctly on the stigma? If not, it could not be considered a true pollinator.

It was visiting Coeloglossum (now Dactylorhiza?) viride :)
