Several other species of walkingsticks also occur in eastern United States. The two-striped walkingsticks, Anisoynorpha bupres- toides (Stoll.), is found in the Deep South, typically in oak stands growing on excessively drained, sandy soil in Florida. Eggs are laid in groups of 8 to 10 eggs, each in small pits dug in the soil. A. ferruginea (P de B.) feeds on various trees and shrubs from southeastern Nebraska and Arkansas through the high country to Georgia and the Carolinas. Diapheromera velii Walsh and D. blatchleyi (Caud.) feed on grasses and tall shrubs. D. velii occurs on the Great Plains; D. blatchleyi, from the Great Plains to the Atlantic Coast. Megaphasma denticrus (Stal.), the giant walking- stick, sometimes attains a length of 150 mm. Its habits are similar to those of D. femorata, but it is apparently never abundant enough to be injurious. FAMILY ACRIDIDAE Short-horned Grasshoppers This family contains most of the well-known grasshoppers, many of which are frequently very destructive to agricultural crops. Ordinarily, they are not very injurious to trees, but they may be seriously damaging during outbreaks. Young trees in nur- series, shelterbelts, and plantations are particularly vulnerable, especially on the Great Plains, in the upper Mississippi Valley, and in the Lake States. The adults are distinguished by their short filiform, or three-jointed, clubbed, antennae; short and in- 57.
