Flesh fly regurgitating food

A flesh-fly "blowing a bubble". The diet of the flesh-fly is very high in water content. The fly regurgitates the liquid portion of the food, holds it whilst evaporation reduces the water content, and then swallows a much more concentrated food meal without the water content. This continues until an appropriate amount of liquid is left for the fly.
