scientific name    Plodia interpunctella    

common name     Indian Meal Moth

habitat
Areas where stored food or grain are located.

seasonality
Can be found at any time of the year.

identification
A small Pyralid with beak-like, porrect palpi and elongated wings having a span of around 15 mm. The basal half of the forewings are light grayish-tan, greenish when fresh, and an outer half that is dull reddish-brown and contains faint, irregular lead-colored lines. The hindwings are grayish-white. The pale-based forewings and habitat make this species easy to identify. Pyralis farinalis, the Meal Moth, also a household pest, lacks the pale-based forewings.

life history
Larvae are wax-like, pale yellow with russet head and shields (Forbes 1923), amongst a silken web which becomes contaminated with frass; pupae in a silken cocoon (Goater 1986). Once an infestation is discovered, the effected food source should be discarded and the area cleaned up. Freezing food products suspected of containing larvae is a good idea.

conservation
Of no concern.

diet info
A major pest of stored grains and grain products such as flour or cornmeal (Covell 1984, Goater 1986).

range
Worldwide. Reported from Area 10 (Edmonton) in Alberta by Bowman (1951). This moth has undoubtedly been found in many homes in Alberta.
