off balance during flight.
|| = How a House Fly works... =
 * ====Pseudotrachea==== ||  || ====A spongey tube which mops up liquid food and draws it into the mouth==== ||
 * ====Labium==== ||  || ====The floor of the mouth==== ||
 * ====Labellum==== ||  || ====The fly's lips==== ||
 * ====Palps==== ||  || ====Used for touching or tasting food==== ||
 * ====Antennae==== ||  || ====Used to feel, smell, detect changes in humidity and air speed when flying==== ||
 * ====Arista==== ||  || ====A bristle which helps the antennae to sense changes==== ||
 * ====Compound eye==== ||  || ====Made up of thousands of tiny lenses which give a wide angle of vision and detect fast movement==== ||
 * ====Prescutum==== ||  || ====The first segement of the thorax==== ||
 * ====Spiracle==== ||  || ====A tiny opening through which the insect breathes in air==== ||
 * ====Calypters==== ||  || ====Scale-like flaps at the base of the wings==== ||
 * ====Halteres==== ||  || ====Help the fly keep balanced in the air. Remove a haltere and the fly goes round in circles!==== ||
 * ====Tarsus==== ||  || ====A foot. Tiny hairs on the tarsus act like human taste buds==== ||
 * ====Pulvilli==== ||  || ====Moist pads on the tarsus which allow the fly to land anywhere without falling off==== ||
 * ====Scutum==== ||  || ====A hard shield to help protect the fly==== ||
 * ====Scutellum==== ||  || ====A triangular shaped section of the exoskeleton on the back of the fly==== ||
