Central Germany, 180m asl., 21st May I think it could be Anthomyzidae? Thank you for your time! -guido gbohne attached the following image:  [242.62Kb] Edited by gbohne on 07-01-2018 19:39 Guido Bohne |

Syrphidae - Melanostoma sp. I think the green haltere are characteristic of this genus but I haven't met all of the syrphids yet. I think that Melanostoma is correct. John and Nini. Naturalists not experts. |

That is interesting! As this female seems t be about oviposition, do you think the offspring is going to be affected by this fungi? -guido Guido Bohne |

I will look for spores or signs of infection. I didn't know that the haltere are normally yellow. I am very interested in this subject. Thank you for posting, Paul. Fantastic info here

Hello, I read some time ago (unfortunately I don't know where anymore). that the halteres tend to become green on mature females when eggs are being developed.

Thank you all very much for IDing. I enjoyed this fruitful discussion. I'll have an eye on green halteres oviposition and fungi-infestations. :-) Best regards, -guido Guido Bohne |

I've seen so green halteres of Melanostoma scalare only in case of two specimens catched toegether (in one place) in USA (Seattle region) very early spring. I thought it is geo-related. I see that from Europe for the first time. |

I thought it is geo-related. I see that from Europe for the first time. here in northwest Germany I often saw/see M. scalare with green halteres over years now. In the beginning I thought it was a difference from M. mellinum.
