I have barcoded one the flies (COX1 sequence). It matches (100%)
Drosophila mercatorum. This species is thought to be native to South America. No wonder I had a hard time to put a name on it.
D. mercatorum has a cosmopolitan distribution and it seems to have reached Switzerland (this would be the first mention to my knowledge)
