Two claws on each foot hook into tiny pits on the surface, while a sticky, hairy pad on each foot helps keep the fly stuck there. Sensory pads with hooked endings give the robot fly extra grip. Flies are so hard to swat because both eyes have about 4,000 six-sided lenses each that can detect even the slightest movement. Most of the robot's head is covered by visual receptors, each pointing in a slightly different direction. A house fly reacts 12 times faster than you.
Flies vomit on their food.
When a house fly feeds, it spits up digestive saliva which it mixes with its meal and then sucks up the mush through its wide, tubular mouth. Inc. All Rights Reserved.
