Gryllus assimilis, commonly known as the Jamaican field cricket and sometimes referred to as the silent cricket among other names, is one of many cricket species known as a field cricket. Its natural habitats are the West Indies and parts of the southern United States, Mexico, and South America, though as a result of widespread breeding programs to supply feeder insects to the pet industry since 2010, it has become available commercially throughout North America and Europe.
