The Almond moth (Ephestia cautella) is a small stored-products pest found in flour, bran, oats and other grains. Adults live for about 10 days after emergence and do not eat, but may drink if water is available. The mating system is polygamous, however many females will only mate once. Mating occurs by placing the abdomens end to end and takes several hours. Caterpillars are cannibalistic and will feed on their siblings. This species is often confused with the Indian meal moth.
