Pyralis farinalis

"Meal moth" redirects here; not to be confused with "flour moth (disambiguation)".

Pyralis farinalis, the meal moth, is a cosmopolitan moth of the family Pyralidae. Its larvae (caterpillars) are pests of certain stored foods, namely milled plant products.

It is the type species of the genus Pyralis, and by extension of its entire tribe (Pyralini), subfamily (Pyralinae) and family. Its synanthropic habits were noted even by 18th- and 19th-century naturalists, who described it using terms like domesticalis ("of home and hearth"), fraterna ("as close as a brother"), or the currently-valid farinalis ("of the flour").
