My first posting here  I have a Digger Wasp I can't identify, the prey it is carrying and a visitor to the nest entrance! First the Wasp and it's prey (I'm not sure if the prey is different in both shots?) -   The Wasp is in close proximity to Cerceris rybyensis and Astata boops on several sites in North London. This is the fly which prompted me to join this forum -  It was visiting entrances to this tiny wasp only - it didn't seem to be interested in Cerceris rybyensis burrows at all. I only saw it disappear into a nest once where it stayed for afew minutes. Many thanks in advance for any of the three id's, Laurence Edited by LPCounter on 18-08-2009 20:31 |

Metopia sp. (Miltogramminae) The wasps seems to be a Crabronidae. |

Nice observation and photos, the prey I think is a chloropid fly. |

Thank you! I had Ectemnius sp as another possibility?  Is the Metopia fly a common parasitoid of these Digger Wasps? |

no! Miltogramminae flies are kleptoparasites of solitary bees and wasps. I.e. they stole the food of the wasps.
