Romalea microptera and Romalea guttata are older synonyms. David J. Ferguson gives some of the history (summarized from an e-mail to P. Coin 6 February 2008):
The name Romalea microptera was granted the status of nomen protectum by the commision on zoological nomenclature--this would gives it official status as the valid name. (This is also the name used by Orthoptera Species File.) The names guttatus & reticulatus have been given the status of nomen oblitum, which makes them officially unavailable for use.
Explanation of Names
Species name guttata is Latin for spotted. Species name microptera is from micro-, small, plus pteron wing, both Greek (Internet searches).
Common name Lubber means "a clumsy or lazy person" (from Middle English lobre meaning lazy, or lout, related to lob). The use for this grasshopper likely refers to their slow movements--with ample chemical defenses, this grasshopper does not need to move quickly.
45-55 mm (adult male), 50-70 mm (adult female)
Distinguished by huge size and vivid yellow/red/black coloration, with hind wings red bordered black. Flightless. Dark red to black nymph (juvenile) with contrasting yellow to red stripes, also distinctive.

Taeniopoda eques is most similar, but found further west. No other species is likely to be confused.
Southeastern United States, including all of Florida. Only lubber in east.
Open pine woods, fields, roadsides, lawns, croplands, esp. moist areas.
All year in Florida, though not as common in winter.
Many herbs and shrubs. Favorite foods are said to include: Pokeweed, Phytolaca americana; Tread-softly, Cnidoscolus stimmulosus; Pickerel Weed, Pontederia cordata; Lizard's Tail, Saururus sp.; Sedges, Cyperus; and Arrowhead, Sagittaria sp. (Grasshoppers of Florida).
Life Cycle
There is one generation per year. During the summer, females lay masses of about 50 eggs in soil excavations about 5 cm deep. Each female lays one to three separate masses of eggs. Eggs overwinter in the soil, with hatching in early spring. Five juvenile instars, each typically lasting 20 days, ensue. Juveniles (nymphs) tend to stick together in groups near a food source. (This probably enhances the effectiveness of their warning coloration.)
Adults are flightless. Coloration is aposematic (warning), apparently this species is distasteful to vertebrate predators. When disturbed, it will spread its wings, hiss, and secrete a smelly fluid from its spiracles (1).
In some regions individuals are prevalently black, in others orange or yellow.
