Hello flyforum, This afternoon I found some little flies in the hot sand around a pool in the Croneforest. They could escape from the attention of some hunting Philonicus albiceps. It was difficult and hot to take a good picture of these flies. Size about 3mm. What kind of (sun-loving)flies are these? greeting Robert, |

If they were in England, I'd say Senotainia conica (Sarcophagidae), but I'm not sure what other species you may have over there! Tony Tony ---------- Tony Irwin |

Sarcophagidae used to be a subfamily of Calliphoridae (the blow-flies), but was elevated to family status. Senotainia is in the subfamily Miltogramminae, a group which specialises in preying on the stores of food gathered by ground-nesting wasps and bees. They are often found near the Hymenoptera nests, waiting for the chance to dash in and lay their eggs. Also, they can be seen "shadowing" their hosts - flying just a few centimetres behind them. In this way they can follow the bee or wasp back to its nest. Tony Tony ---------- Tony Irwin |

Thank you Tony and Nikita for your nice reaction! I saw many little wasps, inspecting holes in the sand with these little flies in their surrounding, so that's not strange what you say Tony! greeting robert |

in this case, which are the male and female? It seems that the eyes touching/ not touching don't apply in this case... |

These flies are related to the Senotainicia family. Nice to hear this specie-name, I did not count on it any more.. Robert, Edited by Robert Heemskerk on 14-02-2007 18:53 |
