Newly-hatched nymphs are pale green, about 8 mm. long, and look like miniature adults. The egg is very hard, oval, seedlike, shiny black or brown, and has a broad white or olive- colored band on one edge. It is about 2 mm. long. Winter is spent in the egg stage and hatching occurs in May or early June. The nymphs feed at first on shrubs such as sweet fern, blueberry, strawberry, and juneberry. Later, they feed on

Newly-hatched nymphs are pale green, about 8 mm. long, and look like miniature adults. The egg is very hard, oval, seedlike, shiny black or brown, and has a broad white or olive- colored band on one edge. It is about 2 mm. long. Winter is spent in the egg stage and hatching occurs in May or early June. The nymphs feed at first on shrubs such as sweet fern, blueberry, strawberry, and juneberry. Later, they feed on leaves of the same trees as the adults. Adults emerge in July or August and feed and lay eggs until the onset of cold weather. In heavily infested stands, the sound of falling eggs striking the ground is much like that produced by raindrops in a light shower. In the South most of the eggs hatch the following year; in the North most hatch the second spring following their deposition. Severe outbreaks occur frequently in the Lake States. They also occur occasionally south of a line drawn from Nebraska to Dela- ware. Trees may be defoliated twice in the same season during severe outbreaks. Branch mortality sometimes occurs in stands heavily defoliated three or four times; continued defoliation for several years may lead to considerable tree mortality (30J^). The. COURTESY IONN. EXl'T.
