One
of the 80 different species of blue morpho is one of the largest butterflies
in the world - and, some might argue, one of the most beautiful. The top
side of its massive wings is a brilliant iridescent blue, but the bottom
side is a dull gray or brown. The blue morpho uses this tricky color combo
in a fascinating survival strategy known as 'flash and dazzle.' As it flaps
its wings, it flashes its bright blue color, dazzling its predators and
showing them exactly where it is, but, just as suddenly, it blends into
the surrounding brown and gray tree trunks as it displays the underside
of its wings, effectively disappearing from its predators view. By the time
it 'flashes and dazzles' again, the predator is very confused.
