Wings for flight give insects great advantage because with them, they can cover
large distances. The wings of a bee or wasp beats about 200 times in a single seconds
creating distinctive humming sound which tells us that they are nearby. The high-U
pitched whine of an approaching mosquito is produced by wings that beat fast still-
up to 500 beats per second.
Air enters an insect's body through its spiraces, openings that lie along the sides M
of its body. It then flows through tiny tubes called trachea. The ends of the tracheal
are so tiny that some of them actually reach right inside the muscle cells. This means
that they can carry oxygen directly to where it is needed the most and take away the
carbon dioxide waste.
