Unusually for insects in the grasshopper family, wood crickets survive for two years. [4] Being flightless, these crickets are limited in their dispersal abilities; males have been found to disperse over 55 m (180 ft) from the woodland edge but females and nymphs did not move nearly so far. [5] Dispersal along the edge of woodland is more possible.
Orthoptera (from Ancient Greek ὀρθός (orthós) 'straight' and πτερά (pterá) 'wings') is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā.
Gryllus pennsylvanicus is known as the fall field cricket. G. pennsylvanicus is common in southern Ontario , is widespread across much of North America [ 3 ] [ 4 ] and can be found even into parts of northern Mexico .
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms , [ 3 ] "crickets" were placed at the family level ( i.e. Gryllidae ), but contemporary authorities including Otte now place them in the superfamily Grylloidea .

Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
Like most cricket species, Teleogryllus oceanicus males produce a calling song to attract potential female mates. Crickets produce the sound of their calls using a "file-scraper" system where, as the male opens and closes its wings, a plectrum (scraper) located on the posterior side of the left wing is rubbed against a filed vein located on the right wing.
