Technical Abstract: We surveyed native cactus plants (Opuntia stricta) at St. Marks National Wildlife Refuge, St. Marks, FL from September 2006 – September 2007 for the invasive cactus moth, Cactoblastis cactorum and the native blue cactus moth, Melitara prodenialis. Every week, we visually counted the numbers and recorded the stage of both insect species from a select number of plants. Pheromone traps were used to collect adult male C. cactorum. Results indicate that the invasive cactus moth, C. cactorum undergoes 3 generations in one year. On the other hand, the native blue cactus moth, M. prodenialis undergoes 2 generations per year.
