Heliothis zia is a species of moth from the family Noctuidae. It is commonly known as the cotton bollworm or corn earworm moth. The species is widely distributed across North America, South America, and Asia. In addition to its common names, the moth has several synonyms, including Heliothis armigera, Heliothis obsoleta, and Heliothis peltigera. These synonyms were given as various taxonomists classified the species differently based on their observations and interpretations of the moth's morphology and behavior. Regardless of the name it is given, Heliothis zia remains an important pest of agriculturally important crops such as cotton and corn, causing significant economic losses for growers.
