How can you recognize the Indian meal moth?

The Indian meal moth is distinguished by its reddish-brown back that has a unique coppery luster. This coloration is a key identifying feature that sets it apart from other pests. Adult moths typically have a wingspan of about 1/2 to 3/4 inch, allowing for easy identification when they are seen in food storage areas where they commonly infest grains, cereals, and dried fruits.

In contrast, the other choices do not accurately describe the Indian meal moth. Its wings are not yellow with black spots or particularly large, and while it does have long antennae, the coloration and lustrous quality of its forewings are the primary identifiers. Understanding these features is essential for accurate identification and effective pest management.
