In the light of evolution, it is very well possible that certain diptera-groups (probably closely related to eachother) have developed this behaviour. It could be a mix of reasons. Or the main reason may be digestion, with an extra opportunity to control bodytemperature.
To get a better idea of this, best we can do is to make solid observations in the field, like I suggested above.
