This looks like one of them Pallopteridae. Who recognises this fly? Jan Willem?

Hi Louis, You are right, it is a female of Palloptera ustulata. When and where did you collect it? Jan Willem |

You're more efficient than a key! This one's also from my kitchen window in Soest (AC 147-466) on 4ix05. Do you know in what substrate the larva lives? Cheers, Louis |

Hi Louis, The larvae live under the bark of trees (Norway spruce, birch, maple, poplar and horn beam). The feed on fungi, but may also become carnivorous, attacking larvae of other Diptera (for example Stegana (Drosophilidae))and bark beetles. |

Well, have a closer look at the tree. As far as I know there are more generations of this species per year! |

Hello Jan Willem and Louis, Is this P. ustulata too ? Last week I saw several of them sitting underneath the leaves of a tree at an open place in a wood near Heerlen. Ben Ben Hamers attached the following image:  [67.89Kb] Edited by Ben Hamers on 22-05-2012 18:54 |

Well it looks similar enough to me, but JW is the expert, as you may have guessed! My specimen has 2 rows of long bristles on femur I, which I can't see in your picture. Maybe sexual dimorphism? |
