Grain beetles are small insects that belong to the family Silvanidae. They are commonly found in stored grains and food products, where they feed on seeds, flour, and other dry goods. These beetles can cause significant damage to food supplies, making them a concern for both consumers and food producers. There are several species of grain beetles, including the rice weevil and the confused flour beetle. They are typically brown or black and can be identified by their elongated bodies and distinctive markings. Effective pest control measures are essential to prevent infestations and protect stored food items.
