Hi Juergen, Baffled by this one I am. I´m thinking this might be the first confincing Oxyna nebulosa I have seen. Do you perhaps have a photo of the head, preferably lateral, but with a good view of the frontal bristles I can´t see properly whether there is just one or more frontal bristles. John |

Hi, John! Sorry, but I only have one additional picture of this fly, which is not better than those posted. I can only upload an uncompressed cutting: Juergen Peters attached the following image:  [129.39Kb] Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Dear Juergen, The habitat is not that important with Tehritids, but rather the hostplants, which of course are to some extent confined to certain habitats. But in the case of O. nebulosa it is either Leucanthemum vulgare or Tanacetum corymbosum, of which the first is very common. And you´re right, the ones you mention are the only three species from Northwest Europe. The problem with this genus is that the chaetotaxy (the number of bristles) is often insufficient to id the species, conclusive id can only be done based on the aculeus. Only tipical specimens can be id from pictures. However this specimen is so different from any O. parietina and O. flavipennis I have seen that I think its O. nebulosa. John |

Hello, John! Many thanks for your explanations. As for the hostplant: Leucanthemum vulgare is indeed very abundant there (and on almost any meadow these days). I don't know Tanacetum corymbosum from here, only T. vulgare, but I have not seen that in this quarry.
