Meal Moth

The Meal Moth (Pyralis farinalis), also known as the Flour Moth or Grain Moth, is a species of moth in the family Pyralidae. It is a common pest of stored products and is found worldwide.

Description

The Meal Moth has a wingspan of 18–30 mm. The forewings are buff, with a broad, dark band near the tip. The hindwings are pale grey. The larvae are off-white with a brown head, and can reach a length of 18 mm.

Life Cycle

The life cycle of the Meal Moth includes four stages: egg, larva, pupa, and adult. The female moth lays her eggs on suitable food material, such as flour or grain. The larvae feed on the food material, then pupate, often within a silken cocoon. The adult moths emerge from the pupae and the cycle begins again.

Habitat and Distribution

Meal Moths are found worldwide, but are most common in temperate regions. They are often found in homes, grocery stores, and any place where grain or flour is stored.

Pest Status

Meal Moths are considered a significant pest of stored grain and flour products. The larvae can cause considerable damage by feeding on the product and by spinning silken threads which can cause the product to clump together.

Control

Control of Meal Moths involves a combination of sanitation, temperature control, and the use of pesticides. Proper storage of grain and flour products can help to prevent infestations.
