[Narrator] If caterpillars
were made for eating, butterflies are made for mating. (soft piano music) Caterpillars are just
juveniles, unable to breed, their lives limited to a leaf or two. Now they are adults, and wings open up a
world of possibilities. They compete and flirt, dancing in the air, circling
skyward in a butterfly ballet. When they do mate, they
join at the abdomen, facing away from each other. How long they stay together varies widely from couple to couple. Incredibly, some partners
stay joined for hours.
