Elementary entomology (1912) Elementary entomology elementaryentom00sand Year: 1912 8o ELEMENTARY ENTOMOLOGY , C ^^'«^^Rlife^ T ^ H r' Fig. 96. A pair of walking-sticks on a birch twig (Photograph by Weed) each Other with avidity. The adults have an extremely long prothorax, with a small transverse head, and long legs. In many tropical forms the wings are bright green and closely resemble leaves, thoroughly protect- ing the insect as it awaits its prey. Walking-sticks, or walk- ing Orthoptera (Phasmidae). The walking-sticks are aptly described by their name; so closely do they resemble the twig of a bush or tree that they are found with difficulty and usually quite by accident. Only one spe- cies occurs in the northern states, which feeds upon the foliage of forest trees and is particularly common on hazel and beech, the body color varying from greenish to brown according to the surroundings. In the tropics are many phasmids of large size and having wings which closely resemble leaves in both color and shape. The large, oval eggs are dropped loose upon the ground, where they pass the winter and hatch the next summer. The next three families all have the hind legs adapted for jumping, and are com- monly grouped together as the jumping Orthoptera. Most of the forms in these three families also have the ability to produce sounds either by their legs or wings. Fig. 97. Eggs of the walk- ing-stick
