House crickets (Acheta doemsiticus) are opportunistic omnivores. They reproduce quickly and make loud, high-pitched sounds at night. These sounds are produced when male crickets rub their forewings together to attract females. Research has shown that female house crickets are capable of discerning which cricket is larger through these songs alone. Cricket sounds also vary by species.
House crickets grow up to 2 cm in length. They are light brown in color and feature three stripes on their heads, as well as long, slender antennae. The wings of the house cricket are held flat against the back and are bent at the sides. House crickets are not native to the United States. They have been introduced from Asia trough their use as pet food and fishing bait. Wild populations of house crickets are most common east of the Mississippi River, although there are also concentrations of crickets in Southern California and in Texas.
Female specimens have long, slender, tube-like structures known as ovipositors. These are projected from the abdomen and are intended for laying eggs. Both sexes have cerci at the back of their abdomens. Young house crickets resemble adults, except for their underdeveloped wings. The life cycle of a house cricket is typically two to three months.
