The famous chirping of the Field Cricket evokes memories of warm summer nights to those who took the time to listen.

Field Crickets are a common site throughout the United States, Mexico and Canada. Warm summer nights bring them out en masse as the males chirp about (up to 30 times a minute) in an effort to attract a female. The noise is a pleasant reminder of the season and will immediately stop if the crickets are approached too closely.

Field Crickets make them homes in the ground, tall grass, or built-up piles of natural lawn debris. They jump away from perceived danger, but sometimes that means right into your legs if you're walking through their habitat. They may startle and tickle, but they are completely harmless.

Field Crickets at a diet of animal remains and plant matter. They provide beneficial services to the ecosystem by eating the eggs and pupae of insect that are considered pests. On the other hand, in large numbers, they can be somewhat of a nuisance in gardens.

Field Crickets are often the species that is purchased at stores and used to feed 'pet' spiders and other insectivores. Anglers may also use them as bait when fishing.
