The Purple Robe Locust, also known as Schistocerca americana, is a species of locust that belongs to the family Acrididae. This insect is native to the Americas, specifically found in the southeastern United States, Central America, and the Caribbean. The Purple Robe Locust is known for its distinctive purple coloration, which is more pronounced in males than females. These locusts are medium to large in size, with males reaching lengths of approximately 2.5 to 3.5 inches (6.4 to 8.9 cm) and females reaching lengths of about 3 to 4 inches (7.6 to 10.2 cm).
Physical Characteristics and Behavior
The Purple Robe Locust has a number of distinctive physical characteristics, including its purple coloration, which is often accompanied by yellow or green markings. The wings of these locusts are typically brown or gray, with a distinctive pattern of veins. In terms of behavior, Purple Robe Locusts are known to be highly social insects, often forming large aggregations during the mating season. These locusts are also skilled jumpers, using their powerful hind legs to cover great distances in search of food or potential mates. The diet of the Purple Robe Locust consists mainly of plants, including grasses, leaves, and seeds.
Habitat and Distribution
The Purple Robe Locust is found in a variety of habitats, including forests, grasslands, and wetlands. These locusts are highly adaptable and can be found in a range of environments, from sea level to elevations of over 3,000 feet (914 meters). In terms of distribution, the Purple Robe Locust is found throughout the southeastern United States, including states such as Florida, Georgia, and Louisiana. These locusts are also found in Central America, including countries such as Mexico, Belize, and Costa Rica, as well as in the Caribbean, including islands such as Cuba and Hispaniola.

Life Cycle and Reproduction
The life cycle of the Purple Robe Locust consists of three stages: egg, nymph, and adult. The female locust lays her eggs in the soil, typically in areas with high vegetation density. The eggs hatch after several weeks, and the nymphs emerge, going through a series of molts as they grow and develop. The nymphal stage can last several months, during which time the locusts are vulnerable to predators and environmental stressors. Once the nymphs reach adulthood, they begin the process of reproduction, with males engaging in complex courtship behaviors to attract females.
Mating and Egg-Laying
The mating process of the Purple Robe Locust is complex and involves a series of visual and auditory cues. Males will often engage in territorial displays, using their colorful wings and aggressive behavior to deter rivals. Once a male has successfully attracted a female, the pair will mate, and the female will begin the process of egg-laying. The female locust can lay up to several hundred eggs at a time, which are then incubated in the soil until they hatch.
