Metamorphosis (noun) - the marked changes in appearance and habit that occur during development, from the growing stage(s) to the mature, adult stage. Butterflies undergo "complete metamorphosis" and their appearance changes completely from the larval to adult stage. Insects which go through a "simple metamorphosis", such as a grasshopper, change only gradually in appearance during these stages.
Like any insect species, the adult butterfly has six legs, two antennae, two wings, a head, a thorax and an abdomen. Caterpillars have a head, followed by a section with six legs and then a section with ten prolegs (some species have less prolegs or none at all). The six legs are its ‘true’ legs: later when the caterpillar becomes a butterfly it will have these same legs. These six legs are pointy and designed to get a hold on the edge of leaves and such. The prolegs only occur on caterpillars and will be disappear when the caterpillar transforms into a butterfly. These legs have suction pads and are especially designed to adhere to flat and smooth surfaces, like smooth leaves.
Essay on “If I were a Butterfly ..
Both butterflies and moths belong to the same insect group called Lepidoptera. In general, butterflies differ from moths in the following ways: (1) Butterflies usually have clubbed antennae but moths have fuzzy or feathery antennae. (2) Butterflies normally are active during the daytime while most moths are active at night. (3) When a butterfly rests, it will do so with its wings held upright over its body. Moths, on the other hand, rest with their wings spread out flat. Butterflies will, however, bask with their wings out-stretched. (4) Butterflies are generally more brightly colored than moths, however, this is not always the case. There are some very colorful moths.
