Synonyms and other taxonomic changes
Tettigidea lateralis (Say, 1824). Synonyms, etc.:
Tettigidea laterale (spelling)
9-16 mm, a bit larger than most others in this family. (1) Another reference (2) reports males as 8-11 mm, females 12-14 mm.
Eyes prominent. Pronotum rounded, extends over head. Tends to extend to tip of abdomen in southern populations, but is shorter in northern. Variably black, gray, brown, or cream. Often dark-sided with wide creamy band on top. Lower face of female is usually dark, that of male is usually a creamy white. (2) Hind femur often has a light spot. Compare front margin of the pronotum to differentiate from T. armata, similar, and found in moist habitats. In T. lateralis front margin is rather rounded. In T. armata it is spined. See Bland, p. 58, figs. 14D, 14E (3) and Helfer, p. 91, fig. 156. (1)

Compare also such widespread species as Nomotetrix cristatus. Pronotum has front margin acutely angled, and is strongly arched. That species is found mostly in dry habitats, and is also smaller, under 1 cm.
Eastern and central North America (including southern Canada) west to Arizona and Colorado. Also south into Mexico and Central America.
Found in both dry and wet habitats: sand dunes, swamps, deciduous and coniferous forests.
All year (North Carolina), all year, except coldest months (Michigan). Perhaps not seen as an adult in mid-summer, e.g., see Insects of Cedar Creek
Life Cycle
Sometimes occurs in migratory swarms. Has long and short-winged forms. One generation per year in north, two in south.
Apparently one of the most widespread and commonly found members of the genus.
