Explanation of Names
The 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
). 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.

Papilionoidea is from Latin papilio/papilionis
, a butterfly or moth. Papilio
is a prominent genus of swallowtail butterflies.
wingspan 7-300 millimetres
Butterflies have thin antennae with "knobs" on the end and are typically active during the day.
throughout North America
world-wide, except Antarctica
Habitats are varied, but adult butterflies are typical of open, sunny places, such as old fields. Some groups are typical of woodlands.
Adult butterflies use their coiled mouthparts to suck nectar from flowers. 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. See World Database of Lepidopteran Hostplants
These insects undergo complete metamorphosis
; that is, each individual goes through four stages: egg, larva, pupa, and adult.
Gender differences: "In some there are dramatic differences in pattern, scaling, structure, or shape, but in most it is more subtle. In some groups (i.e. Swallowtails) you can tell just by seeing the side or bottom of the tip of the abdomen, because the male claspers (=valvae) are very visible. In other groups (including the subfamily Nymphalinae) the claspers are harder to see, but are still there, and affect the shape of the abdomen. The tip of the abdomen in males has the pair of claspers, which even if hidden by a clump of hair-like scales, gives the tip of the abdomen a blunt look from the side, and usually a slightly squared or bilobed look from above or below (nearly pointed in females). Also, the abdomen of females tends to be plump and rather symmetrical in shape, widest near the middle or sometimes the base, while the abdomen of the males is usually more slender and especially from the side less symmetrical in shape, with a tendency to be slightly widest near the end. Often males have proportionately longer abdomens, but this is more noticeable in some groups than others. In most of the family Nymphalidae, the males have the wings less full and less rounded, often somewhat more angular in shape. The hind wing of males is often distinctly more angular at the hind end (near the tip of the abdomen), while in females it is usually much more rounded. On average males tend to be smaller than females, and often more active and more inclined to chase after things or act aggressively." Comment by David J. Ferguson,
