fields, lawns, commercial crop plantations
Mar-Oct in se. US
nymphs and adults feed on forage, lawn, wild, and crop grasses
Life Cycle
overwinter as adults among weeds/grasses near fields; adults emerge in spring and lay eggs singly behind leaf sheath or in soil at base of small plants; eggs hatch in a few days; nymphs feed on all parts of host plant; 5 nymphal instars; 2-3 generations per year
This feeding prevents normal growth and results in dwarfing, lodging, and yield reduction. Severe infestations during early development may cause plants to wilt and die prematurely.
