What is Moth?

 

The moths are a paraphyletic group of insects related to the butterflies and belonging to the order Lepidoptera. Most lepidopterans are moths and there are thought to be approximately 160,000 species of moth,  many of which are yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species.

 

While the butterflies form a monophyletic group, the moths, which comprise the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidotera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.

 

Although the rules for distinguishing moths from butterflies are not completely hard and fast, one very good guiding principle is that butterflies have thin antennae and (with one exception) have small balls or clubs at the end of their antennae. Moth antennae can be quite varied in appearance, but in particular lack the club end. The divisions are named by this principle: "club-antennae" (Rhopalocera) or "varied-antennae" (Heterocera).

 

Moth larvae, or caterpillars, make cocoons from which they emerge as fully grown moths with wings. Some moth caterpillars dig holes in the ground, where they live until they are ready to turn into adult moths.
