Picture-Winged Fly

This awesome fly looks like some sort of alien insect wearing a gas mask. They have two distinct white triangles on the front edges of its wings. It's very cute when it walks because it moves its wings in rowing motion, as if they were oars.

Picture-winged flies have an interesting behavior called "bubbling". This means that they regurgitate a drop of their meal, and hold it in their mouthparts for a while before reingesting it. Scientists think that bubbling evaporates water from the droplet of regurgitated food, thus concentrating the meal into a smaller, more digestible volume.
