These lubbers are the largest grasshoppers I have ever had the good fortune to observe. They can afford to be larger and more noticable than most of their Orthopteran relatives because they have toxins derived from plants they ingest, which they advertize via the bright orange warning coloration seen here. They have few predators as a result of their effective chemical defense system, and are therefore abundant and ubiquitous in disturbed roadsides along the wetlands of Everglades National Park. One of their few predators is the loggerhead shrike, sushi chef among birds, who has evolved the ingenious hunting strategy of impaling the lubbers on barbed wire and thorny scrub, letting the poisins drain, evaporate, or decompose, preparing a detoxified meal of lubbers the size of miniature lobsters.

Genus and species: Romalea guttata
