Ichneumon sp

This tiny Ichneumon wasp flew past me with its hind legs dangling underneath it. I thought it was an ichneumon but I had never seen one like this before. On equiring further I was advised by a friend from the 'animal toy forum' that there are approx. 2,400 species of ichneumonids in Great Britain. Hence the reason I can't name it but boy was I exicited on finding a new ichneumon I had never seen before. Enjoy and let me know if you know its name.
