[Syrphidae] Syrphidae alert

[Ante Vujić]

Dear all,

I would like to share with you field experience from this season in 
Serbia. We have less than 50% of species usual for this time of year in 
flight and most of present species are with very small populations. 
Aphidofagous species are most numerous, especially Syrphus. Very low 
number of Cheilosia and Merodon. This can be related to long period 
without rain during spring, but still. During my 40 years experience in 
field work, this is the strangest season.

Best regards,

Ante
