Fun Butterfly facts.

BREATHING - Butterflies do not have a lung system like humans do, but instead take in oxygen through tiny openings along their abdomens called spiracles.

These openings tightly close up to prevent foreign matter from getting inside the body, but open periodically to allow oxygen inside. When a butterfly is in flight the spiracles open and fresh air is pushed into the body. It is then transported through a system of tunnels or tubes called trachea. This is why you’ll see butterflies periodically open and close their wings while they are resting.

“STEERING” - Adult butterflies have “compound” eyes which allow them to distinguish colour and motion better than humans’ “simple” eyes can. Each of the hundreds or thousands of lenses on the surface of the eye receives an image, so butterflies can see in all directions at once and are adept at avoiding collisions. Sensory organs located on the antennae also help butterflies judge the distance between obstacles. Notice how they seem to be flying straight at your head, then veer off at the last instant. Butterflies are particularly aware of motion, so visitors who extend their arms in hopes of a butterfly landing are actually presenting more obstacles to be avoided!
