Explanation of Names
The exact origin of the word butterfly is uncertain. Modern English butterfly is from Middle English boterflye, thence from Old English buttorfleoge, a compound word, corresponding to butter + fly. There are (at least) three theories as to the connection of butterfly to butter:
1-Butter refers to the color of yellow species, i.e., the Sulfurs, in particular, European species such as the Common Brimstone (Wiktionary--butterfly). Under this scheme, the meaning of the compound buttorfleoge is "yellow flier" (Partridge, 1958). It is not clear why the sulfur family was chosen to represent, linguistically, the group.
2-Butterflies are attracted to milk and butter churns. (Alternatively, there were related folk tales that butterflies were spirits that stole cream.) The German word for butterfly, schmetterling has, perhaps, similar connotations (Butterfly etymology).
3-A Dutch word for butterfly is (or was) boterschijte, allegedly referring to the color of its excrement, (Oxford English Dictionary?, quoted in various Internet sources). This is, perhaps, a linguistic connection, but it is not clear how! (Dutch and English are closely related languages.) This derivation is rather implausible, since butterflies do not excrete solid waste, but the linguistic parallel is suggestive.
For a good summary, see the discussion from A World for Butterflies and also Scott (1).
Papilionoidea is from Latin papilio/papilionis, a butterfly or moth, and of course Papilio is a prominent genus of swallowtail butterflies.
Size
0.7 - 30.0 centimeters
Identification
Butterflies have thin antennae with "knobs" on the end and are generally active during the day.
Range
throughout North America

world-wide, except Antarctica
Habitat
Habitats are varied, but adult butterflies are typical of open, sunny places, such as old fields. Some groups are typical of woodlands.
Food
Adult butterflies feed on nectar sucked from flowers with their coiled, sucking mouthparts. In the process they may transfer pollen from one flower to another, and many plants depend on butterflies or moths for pollination.
Most caterpillars eat the leaves of certain plants.
Life Cycle
These insects undergo complete metamorphosis, that is, the young go through four stages: egg, larva, pupa, and adult:
