Abstract

This chapter discusses crickets, which are insects in the order Orthoptera that comprise the ensiferan family Gryllidae. Crickets have long thread-like antennae, two slender tactual abdominal cerci, three tarsal segments, and some bulbous sensory setae basally on the insides of the cerci. No other insects share all these features; the last is closest to a single defining trait, shared by only certain Stenopelmatidae. The forewings of crickets, when present, are typically stiff and leathery; the hind wings are membranous and fold fan-like under the forewing when not being used. They occur almost everywhere on the earth between the regions of taiga vegetation that start at approximately 55° North and South latitude. Some seem to feed almost entirely on vegetable matter, yet sometimes consume carrion and even ferociously kill and eat other insects. Several species frequent human dwellings and refuse heaps, most notably A. domesticus and the decorated cricket, Gryllodes sigillatus. Subterranean species feed mostly on roots and can be injurious when abundant in crops, gardens, lawns, golf courses, and newly reseeded forests.
