The Indianmeal moth is named for infesting a type of Indian cornmeal, though they will feed on many other things. They are sometimes confused with clothes moths, but they are easy to distinguish if you know what to look for. Indianmeal moths are colored tan to gray, with a reddish brown band on their wings. The band on their wings also has somewhat of a copper shine to it.
Clothes moths are a solid, subdued color.
These meal moths are also not really active in the daytime, and are attracted to light. The moth larvae are slightly bigger than the adults, and do all of the damaging feeding. They are mostly colored white, but can have different tints of color depending on what food they are eating. Foods they will eat include cracked or coarse grains, dried fruit, cereal, pet food, and shelled nuts. The larvae aren't very good at chewing through packaging, but can get in through small openings.
