Wednesdy I will leave for the bi-annual international workshop on flower 
flies in Serbia.

When I get back I will see about finding references for you.

Rearing syrphids in captivity is a mixed bag. Some species are easy to rear 
and are routinely used in laboratories (Eristalis tenax and Episyrphus 
balteatus) and for greenhouse pollination. However, USDA attempts at using 
Cheilosia for the biological control of thistle failed as they could not get 
colonies going. Males would simply not mate in a cage.

What you need to do urgently is spend time in the field watching Heringia 
calcarata, seeing how it mates, etc. For example, do the males hover and 
then mate with the females in the air? Or do the males meet the females on a 
leave and simply climb on board, etc

More later ....
