A good find from back in September this year, the Ivy Waspgrabber (Leopoldius signatus). A fly in the family Conopidae, members of which parasitise bees and wasps, ambushing them and laying their eggs inside them. The larvae then feed on the insides of the host, often changing its behaviour. This species is thought to use the Common Wasp (Vespula vulgaris) as the host.
