Fall Army Worms are native to the tropical regions of the western hemisphere and are a constant threat to southern turf. They normally winter successfully in Southern Florida and Southern Texas. The adult of the Fall Army Worm is a shaded gray and brown moth. Adults are nocturnal, and are most active during warm, humid evenings. Here in South Florida adults can be found from April to December and sometimes during the winter. They are strong fliers, and disperses long distances during the summer months. Adult moths only live around 10 days and lay most of her eggs within the first four to five days. Eggs hatch in 7 to 10 days or 2 to 3 days in July and August. Larva takes as little as 12 days to mature in July or up to 30 days in October. The pupa stage only takes 8 to 9 days and there could be as many as 3 to 4 generations each summer here in South Florida.
