The insects of this order may all be collected by the use of the sweep-ing net. Some of the families are attracted to light, as certain of theroaches and green locusts, or Katydids (Locuntidtr). Our commonroaches (Blattida-) are cosmopolitan insects, and infest species are also found about ponds, under rotten logs, the bark oftrees, and particularly in decaying vegetable matter. In the tropics thespecies are very abundant, but aside from the domestic forms, theyoccur rarely in northern latitudes. The collection of the egg-cases(ootheca) is important as they furnish many interesting Mantidae, of which the Preying Mantis fPhasmomantis curolinu) is.

ThePhasniidre or Walking sticks are herbivorous and may be collected in themdst of vegetation by sweeping or by the hand. The crickets (Gnjl-lid(c) frequent, for the most part, moist situations. Certain forms, likethe Mole-cricket and the Jumping Water-crickets (Tryddctylttx spp.),burrow in moist soil and occur in numbers near the edges of ponds andwater courses. The katydids and locusts are abundant on low shrubsor trees and in pasture and meadow land, but are most numerous inthe somewhat dry, arid regions of the West.
