Eastern lubber grasshopper

Definition

A large, flightless grasshopper, Romalea microptera, native to the southeastern and south-central United States, recognized by its striking aposematic coloration—typically black with yellow, orange, or red markings—and its slow, clumsy locomotion. The species is chemically defended: it sequesters toxins from host plants and produces defensive secretions from thoracic glands, making it unpalatable to most vertebrate predators. Adults are among the largest North American grasshoppers, reaching 50–70 mm in body length.

Etymology

From "lubber," an archaic term for a clumsy, slow-moving person, referring to the insect's sluggish, terrestrial habits and inability to fly; "eastern" distinguishes it from western lubber species.

Example

Eastern lubber grasshoppers often aggregate in dense groups during nymphal stages; their bright coloration advertises chemical defenses rather than providing camouflage, a classic example of aposematism in orthopterans.

Synonyms

• Georgia thumper

Usage Notes

The common name refers specifically to Romalea microptera under traditional circumscription; some recent taxonomic treatments subsume Taeniopoda into Romalea, which would expand the genus to include roughly a dozen species distributed from the southern United States through Central America. The species is frequently encountered in wet meadows, roadsides, and agricultural areas, where its polyphagous feeding can damage ornamental and crop plants. Despite being flightless, it disperses primarily by walking and jumping, with nymphs often forming cohesive aggregations that can alarm gardeners unfamiliar with their defensive chemistry.
