The cactus moth is a destructive pest that poses a serious threat to cactus plants. Its presence can lead to reduced productivity, stunted growth and eventually, death of the plant. There are several synonyms for the cactus moth, including the Opuntia moth, Prickly pear moth, and Harrisina cactus. These synonyms refer to the same insect that belongs to the family Erebidae. The cactus moth can be identified by its brown and white wings that are adorned with dark bands. It is important to control the spread of this invasive species to prevent further damage to cactus plants and their ecosystems.
