Hi Mike,
this Cheilosia belongs to the C. longula species-group.
Three species are reported from Austria within this group (C. soror, C. scutellata, C. longula).
Among other, we must have a closer look at the anterior anepisternum to be sure what species it could be. My guess: C. soror, female.
Greatings, Helge
