hello flyforum, First I though this was Polietes lardaria, but I am not convinced. What about the colour of the anterior spiracle? Is it posible that this is some other Polietes species? Robert, Robert Heemskerk attached the following image:  [180.04Kb] |

I'd say you are right, Robert - correct name Polietes lardarius

Compare with: http://www.diptera.info/photogallery.php?photo_id=1274 Also P.meridionalis is Submediterrenian species less probable in the Netherlands Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I do not agree with that, Nikita. I'd say P. meridionalis is pretty common in the Netherlands, at least where I live (in the center of the country). Since you identified my first meridionalis (photos are now in the gallery), I have found and photographed many more at the same location and at other locations. Mostly in half open areas with older trees, water and grassland nearby. I have the impression that meridionalis is more common here than lardarius. http://slamenietd...web-log.nl |

Maybe P. meridionalis can be pretty common here and there?!... I think flyspecies can differ a lot in occurence, so are the biotopes. |

Is P. meridionalis on the British list yet? I caught a Polietes last week (North Wales) that keyed to lardarius (hairs on the little plate between the front legs, prosternum?) in Fonseca's RES key, but had a brown face and bright yellow front spiracle, which according to Gregor et al. makes it meridionalis. So I looked out a "lardarius" from this area two years ago, and it also has a brown face and yellow spiracle. Both are females so the leg spine character is no use. And both were taken late in the year (Nov and Dec) so I was wondering if lardarius tend to be browner at this time of year. But if meridionalis is common in The Netherlands, Wales does not sound so unlikely. John Bratton |
