OVIPOSITING METHODS EQUALLY VARIED The egg laying habits within the Orthoptera exhibit diversifications ranging from a simple type to a highly specialized one. The walking sticks have the simplest method, dropping the eggs indiscriminately on the forest floor. The crickets insert their eggs irregularly into rotton wood, bark or the soil. The snowy tree crickets show considerable care in egg layingâ the female makes a small hole in a branch of a tree, deposits the egg in the bottom and covers it first with a mucilaginous secretion and then with chewed-up bark. The meadow katydids and coneheads deposit their eggs in the sheathes of grass stems and similar Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Illinois.
