Hello a very little fly, always movings his wings when walking on Heracleum spondylium length of the body , about 2 mm Boulonnais, Northern France I thought palloptera, C Thirion said Opomyza, the second name seems better Somebody have an idea ?? Best regards Alain Vadet  |

Hai Alain, This one is indeed a Pallopteridae. In fact it is a Palloptera sp. In Holland there are only 9 species, but I can't tell you which one it is! Greetings! Greetings, Gerard Pennards |

The details are not clear enought to say with certainty, but it maybe Palloptera trimacula. In this species the anterior crossvein should not be infuscate and this is exactly the character which is not quite clear. Otherwise it well agrees with that species. Maybe Jan Willem (JeeWee) can decide on other characters.

Hi Alain, I agree with Gerard! It is a pallopterid. My first guess is that it is a specimen of Palloptera trimacula (Meigen, 1826). Do you have more pictures of this specimen from other viewpoints? That might help to get it possitively identified! Jan Willem van Zuijlen |

If the weather is good enough this week end I will go back to the same place where they were about 20-30 flies on each Heracleum, to take other picutres and caputre some flies Best regards Alain Vadet |

Hi Alain, Again very nice pictures. In my opinion it is save to identify this species as Palloptera trimacula. This species is known to be found on Umbelliferae. Furthermore Parmenter (1951, 1960) raised imagines from puparia found in December under the epidermis of the stalk of Angelica silvestris. Parmenter, L., 1951. Notes on the Distribution of Pallopteridae in Britain. -- Ent. Record, 63(12): 304-306. Parmenter, L., 1960. A Further List of the Diptera of Bookham Common. Lond. Nat., 39 (1959): 66-76.
