Which of the following pests is known for flying in a zigzag pattern when disturbed?

The Indian meal moth is particularly noted for its unique flight pattern, often described as a zigzag motion when it becomes disturbed. This erratic flying behavior can be attributed to its search for food sources or when it feels threatened. Indian meal moths are common pests found in homes, especially in areas where food products, such as grains or dried fruits, are stored.

Other insects listed do not exhibit this specific flight behavior. The lesser grain beetle, while a pest of grain, has a more direct flight pattern. The sweat bee, which is a type of solitary bee, tends to fly in a more consistent flight manner, and yellow jackets, being wasps, usually fly in a straight line toward their nests or food sources. Understanding these behavioral traits helps in pest identification and management strategies.
