Parasitic wasp

It was a slightly drier and warmer day to be surveying a Northamptonshire hay-meadow with Alex. There was a good quantity of one of my favourite members of the Carrot Family, Pepper-saxifrage, which has umbels of delicate sulphur-yellow flowers. It was proving very popular with a range of Hymenoptera, including large numbers of this rather handsome parasitic wasp and several species of sawflies.
