Artist's Description

Species Romalea microptera – Eastern Lubber Grasshopper
Size
45-55 mm (adult male), 50-70 mm (adult female)
Identification
Distinguished by huge size and vivid yellow/red coloration (adult, light phase, southern Florida). Flightless. More northern adults are darker. Juvenile (nymph) is black with yellow (or red) stripes, also distinctive.
Range
Southeastern United States, including all of Florida. Only lubber in east.
Habitat
Open pine woods, fields, roadsides, lawns, croplands, esp. moist areas.
Season
All year in Florida, though not as common in winter.
Food
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.)
Remarks
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
