Indian meal moth (Plodia interpunctella)


The Indian meal moth has developed into the most frequently occurring moth in industry, commercial trade and human habitations. The adults have a wingspan of 20 mm. The part of the forewing next to the body is yellow-grey, the wingtip red-brown to copper red. One females lays 200 to 400 eggs. The larvae grow to a length of 16 mm and vary in colour depending on what they feed on between whitish, greenish and reddish.


Despite its name, the Indian meal moth eats all kinds of foodstuffs; the name “meal moth” reflects this. These animals are found, for instance, on dried fruit, nuts, chocolate, grain, spices, etc. The larvae eat the germ out of the grains; holes are eaten in foodstuffs. The foodstuffs are heavily contaminated by cocoon spinning and faecal crumbs.
