Hi Mike

Sorry, not sure if this is the kind of info that might help - my first hoverfly experience is ongoing, but I am currently raising Syrphus ribesii at 21 degrees, (16:8 light : dark). They were fed every 24 hours with fresh aphids and have taken 8 - 11 feeding days to reach pupation shape. (They are currently in pupation). Aphids used were Sitobian avenae. 

Regards,  Matt

Hi Folks
can anybody help with temperature threshold info for syphids to allow
day-degrees to be to used to model development time of Eristalis,
Melanostoma and Melangyna species?
Your help would be much appreciated.
