Explanation of Names

Common name Indian Meal Moth is from another name for corn meal, which the moth's larvae were found feeding on by Asa Fitch (1809-1879), the New York State entomologist who coined the common name.

Specific epithet interpunctella is Latin meaning "well divided, pointed." (1)


The only species in this genus in North America.


Wingspan 13-20 mm.

Forewing length 5-8.5 mm. (2)

Larva to 12 mm.


Adult - bicolored forewing with the basal half light gray or whitish, and the distal half reddish-brown, coppery, or dark gray. Hindwing white or pale gray.

Larva - body whitish to yellowish, head yellow to reddish-brown, short prolegs on abdominal segment 3-6 and 10.


Native to South America; now cosmopolitan.


Larvae are found in stored food products; adults are found indoors wherever food products are stored. In warmer environments may be encountered outside where it likely feeds on waste orchard fruits and seeds. (2)


Year-round indoors.


Infests a wide variety of stored food products such as flour, oatmeal, dried fruits, seeds, nuts, powdered milk, biscuits, chocolate, and bird seed.

Life Cycle

Several generations per year indoors. Can complete the entire life cycle in as little as 18 days. (2)


Larvae spin silken threads as they crawl through stored products, creating a matted layer of product, frass, and pupal cases.

Комнату освещали лишь странные оранжевые блики. В воздухе пахло жженой пластмассой. Вообще говоря, это была не комната, а рушащееся убежище: шторы горели, плексигласовые стены плавились.
