Romalea microptera (Beauvois) (Insecta: Orthoptera: Acrididae)
The Eastern lubber grasshopper, Romalea microptera (Beauvois), is a large colorful flightless grasshopper that often comes to the attention of Florida homeowners. It is native to Florida and the Southeastern Coastal Plain of the United States.
Because of its size and coloration even one individual in a garden is conspicuous, but occasionally local populations explode to such an extent that the grasshoppers can seriously damage ornamentals, row crops and citrus groves. Such population explosions are the result of factors such as weather and rates of parasitism by beneficial insects that normally limit population growth.
Lubber grasshoppers have only one generation per year and with the notable adults being present in late summer. They tend to prefer low, moist areas for breeding but can disperse into any nearby habitat. They will feed on many different kinds of plants but seem to favor amaryllis and its relatives.
