Filth flies cannot chew; they have to suck up their food.
Flies do not have eyelids; they have to rub their eyes with their feet to keep them clean.
Flies taste, smell, and feel with the hairs that cover their bodies. Flies actually taste what they walk on.
Flies can walk on smooth surfaces using sticky soft pads on their feet that act like glue. This allows them to walk on vertical glass surfaces and even upside down
Chocolate comes from fruits of the cacao tree of South America. Its flowers are pollinated by the chocolate midge, a tiny fly less than 1/8 inch long. Without this fly, there would be no chocolate.
