It is interesting for me that Peter Tschorsnig has rarely seen Opesia grandis, in some years I have collected a lot of them in Lithuania, but I noticed that they seem dissapearing, when previously cultivated and neglected meadows with dry conditions overgrow by a forest, or maybe its connected with some other reason.
On the other hand, species as Periscepsia carbonaria, Stomina tachinoides and Thelymyia saltuum I have seen in historical Lithuanian materials only. I am interesting about the status of these three in the other countries?
