BUTTERFLY
Butterflies have the
typical four-stage insect life cycle. Winged adults lay eggs on the food plant
on which their larvae, known as caterpillars, will feed. The caterpillars grow,
sometimes very rapidly, and when fully developed pupate in a chrysalis. When
metamorphosis is complete, the pupal skin splits, the adult insect climbs out
and, after its wings have expanded and dried, it flies off. Some butterflies,
especially in the tropics, have several generations in a year, while others
have a single generation, and a few in cold locations may take several years to
pass through their whole life cycle.
