Romalea mycroptera
The lubber is surely the most distinctive grasshopper species in the southeastern United States. It is well known both for its size and its unique coloration. The wings offer little help with mobility for they are rarely more than half the length of the abdomen. This species is incapable of flight and can jump only short distances. Mostly the lubber is quite clumsy and slow in movement and travels by walking and crawling feebly over the substrate.
Eastern lubber grasshoppers seem to prefer open pine-woods, weedy fields and the weedy vegetation along roadsides. Occasionally, on rural highways in the central portion of the state, enough flattened lubber grasshoppers will accumulate on the road to cause a minor slick! The accumulation of weedy plant species along drainage ditches within citrus groves and vegetable fields will sometimes attract lubbers, which in turn end up feeding on the cultivated crops as well. Lubbers may often invade residential areas and feast on certain ornamental plants, especially amaryllis and related flowers.
Eastern lubber grasshoppers possess a variety of abilities to defend themselves. Their bright color pattern is a warning to predators that the lubber contains toxic substances. Indeed, there are several records attributing the demise of individual birds to failure to exercise caution when selecting prey items. Also small mammals such as opossums have been known to vomit violently after ingesting a lubber, and to remain ill for several hours. However, shrikes are reported to catch and kill lubbers. If the red, yellow, and black coloration fails to keep a predator at bay, then the lubber may secrete a foamy spray from the thoracic region (the portion of the body where the legs and wings are attached.) This spray consists of a number of compounds, some of which, are irritants. This bubbly froth is accompanied by a relatively loud, frightful hissing sound. The insect contracts the abdomen to force air out of the spiracles along with the defensive secretion. The sound is produced as the spray is being forced out of these tiny holes in the thorax called spiracles. Eastern lubbers, like most all grasshoppers, can also regurgitate recently consumed plant material. This regurgitant is mostly liquid and has a dark brown color. This is commonly referred to as "tobacco spit." The tobacco spit is partially digested food material along with some semi-toxic compounds from the insect's crop region. This substance can easily stain clothing.
