Cactoblastis cactorum, commonly known as the Cactus Moth, South American Cactus Moth, or Nopal Moth, is native to Argentina, Paraguay, Uruguay, and southern Brazil. It is one of five species in the genus Cactoblastis that inhabit South America, where many parasitoids and pathogens control the expansion of the moth's population. This species has been introduced into many areas outside its natural range, including Australia, the Caribbean, and South Africa. In some locations, it has spread uncontrollably and was consequently classified an invasive species. However, in other places such as Australia, it has gained favor for its role in the biological control of cacti from the genus Opuntia.
