House cricket

Description:

The house cricket is typically grey or brown in color, growing to 16–21 millimetres (0.63–0.83 in) in length. Males and females look similar, but females will have an ovipositor emerging from the rear, around 12 millimetres (0.47 in) long. On females, the cerci are also more prominent.There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure including jumping hind legs.

Notes:

There are four types of cricket song: The calling song attracts females and repels other males, and is fairly loud. The courting song is used when a female cricket is near, and is a very quiet song. An aggressive song is triggered by chemoreceptors on the antennae that detect the near presence of another male cricket and a copulatory song is produced for a brief period after a successful mating.
