did you know?: Flies

• Houseflies’ feet are 10 million times more sensitive to the taste of sugar than the human tongue.
• Houseflies walk upside down using glue-oozing toe pads.
• The favorite color of the housefly is red.
• Despite years of trying, no researcher has ever been able to teach flies anything — fish, ants, snails, cockroaches, even worms all can learn … but never flies.
• A fly’s vision is only sharp for 24-36 inches.
• Despite having 4,000 lenses in each eye, flies have bad vision but are good at detecting movement; move slowly and they don’t see you as a threat — a useful tip to know when stalking flies.
• If a housefly spots a group of flies, he will join them. That’s why sticky fly paper works so well — when a few flies get stuck, soon all the others rush over to check out the crowd.
