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.
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.
