Eastern lubber grasshopper

The Eastern lubber grasshopper, scientifically known as Romalea microptera, is a large species belonging to the Romaleidae family. These insects are well-known for their bright coloration and their ability to produce foul-smelling, toxic secretions as a defense mechanism against potential predators.

This pest is a generalist herbivore, capable of consuming a wide variety of plant materials. It frequently targets ornamental plants, citrus trees, vegetable crops, and various field crops. Because of its large size and high appetite, even a small group of lubbers can cause significant structural damage to vegetation.

The life cycle of Romalea includes the egg stage, several nymphal stages, and the adult phase. Eggs are laid in clusters within the soil during the late summer, where they undergo diapause throughout the winter. Nymphs emerge in the spring, molting several times before reaching their full adult size by mid-summer.

The damage caused by these grasshoppers is primarily characterized by severe defoliation. They consume leaves, stems, and fruits, leaving plants bare and vulnerable. In agricultural settings, they can cause rapid and widespread economic loss if their population reaches high density, particularly in susceptible young crops.

Effective management requires an integrated approach to minimize the impact of the pest. Key strategies include:

• Tilling the soil in the fall or winter to expose and destroy egg pods.
• Hand-picking nymphs and adults in small home gardens where infestations are localized.
• Applying recommended insecticides during the early nymphal stages when they are most vulnerable.
• Maintaining healthy plant density and clearing weeds that may serve as alternative food sources.
