The Nymphalidae, also called brush-footed butterflies or four-footed butterflies, are the largest family of butterflies.

They are known to stand on only four legs while the other two are curled up.
Some species of these, these forelegs have a brush-like set of hairs.

Lepidoptera is a combination of two Greek words:
• Lepis (λεπίς): meaning "scale"
• Pteron (πτερόν): meaning "wing"

The literal meaning of Lepidoptera is "scaly wings."

Nymphalidae:
- Ancient Greek νύμφη (nýmphē meaning Water nymph, Naiad, or young maiden or young girl) which gives its origin to the Latin nympha which is used to name a butterfly genus Nymphalis.

The word "butterfly" is from Old English buttorfleoge, possibly from the pale butter color of some species' wings.
The word "moth" is from Old English moððe from Common Germanic and German Motte meaning "moth".
The word "caterpillar" is from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose (from Latin cattus, "cat" + pilosus, "hairy").
