Hi, Some days ago I watched a Spiny Digger Wasp, Oxybelus argentatus, dragging its usual prey, a Thereva to a suitable place where to bury it. There was also another careful watcher whom I had already observed earlier on sandy places preferred by Crabronidae wasps. It was a small Sarcophagid of Miltogramminae. The wasp was not amused by its presence, but the fly, unimpressed, stayed on its place. Its behaviour resembled that of Metopia, a male of which was also nearby. However, Metopia has bigger antennae, so is this a Miltogramma? And does it parasitize the wasp's prey or brood? Many thanks for information, Sundew Sundew attached the following image:  [165.52Kb] Edited by Sundew on 14-07-2009 11:02 |

Friends, I am delighted you like my newest movie! (BTW, I have so many shots I could really combine them to a film ) Among the actresses, Thereva received the most thankless part... Now I'm waiting for the second script author, as I'm a bit in doubt about Senotainia conica. Liekele IDed this species in a former thread of mine (http://www.dipter...d_id=15039), and this fly looked different. The upper one has a brownish frons, S. conica had a grey one. Well, I really wonder who my leading lady is! |

Very, very nice pictures. This Senotainia looks different because it is a female (on the other thread it was a male) and there is some variation in colour. I think this must be Senotainia conica. Some (older) literature mentions relations between Miltogramma and Sphecidae. Most recent and traceable observations of Miltogramma always - to my knowledge - refer to Apidae as hosts of Miltogramma. It seems very unlikely to me that Miltogramma switches in food from vegetarian to non-vegetarian. A movie about Miltogrammine flies is a great idea. University of Wageningen made a movie but it is considered lost. I have never seen it. Liekele |
