Thanks Joel
The thing that got me wondering, is that this one is twice the size of this other one I saw.

Size
There is often extensive variation in the size of individual bee flies of the same species. I've recorded specimens from 5 - 10 mm long for this species, and even larger ranges for some other species. It's most likely due to variation in the size of the prey for the developing larvae.
