32 University of Vermont Extension EL 32 Crickets by G.R. Nielsen, Former Extension Entomologist, Plant and Soil Science Department Crickets are often late-summer or fall invaders of houses and other buildings. Their chirping can be a nuisance because of its annoying nature or its superstitious significance to the listener. Field crickets develop outside and enter homes in the fall for shelter. Crickets are nocturnal, hiding in dark places during the day.
Crickets have simple metamorphosis or development.
The young, or nymphs, molt to look more like the adult, as with grasshoppers. They belong to the family Tettiigonidae, along with the katydids, mormon crickets, cone-headed grasshoppers, and others. Those humpbacked, wingless grasshoppers bear some resemblance to true crickets, however. They live in dark, moist places, under stones and rubbish, and in cellars, caves, the walls of wells, etc. They are nocturnal in their habits.
