Answer 3

Only humans make noise. Crickets make cricket music. This is the way crickets tell other crickets what is going on. A cricket maybe be hungry, looking for a mate or protecting it's turf. So it sings a lovely song.

Consider yourself lucky to hear the crickets sing.

Answer 4

It is a mating call from the males; they are looking for a female cricket to have sex with. The male cricket creates the noise by rubbing his legs on his wings.

Crickets are attracted by lights like moths and during mating season they will flock to all night shopping centers in huge hordes for a better chance to find a mate. The males need to send out a audio signal to attract or please their women. Moths use sent; but crickets make the loud chirping noise.

According to Wikipedia: http://en.wikipedia.org/wiki/Crickets
"Crickets, family Gryllidae (also known as "true crickets"), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (family Tettigoniidae). They have somewhat flattened bodies and long antennae.

Crickets are known for their chirp (which only male crickets can do; male wings have ridges or "teeth" that act like a "comb and file" instrument). The left forewing has a thick rib (a modified vein) which bears 50 to 300 "teeth". The chirp is generated by raising their left forewing to a 45 degree angle and rubbing it against the upper hind edge of the right forewing, which has a thick scraper (Berenbaum 1995). This sound producing action is called "stridulation" and the song is species-specific. There are two types of cricket songs: a calling song and a courting 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. Female crickets have a long needlelike egg-laying organ (ovipositor).

Crickets chirp at different rates depending on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (approx. 60 chirps a minute at 13°C in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's Law. In fact, according to this law, it is possible to calculate the temperature in Fahrenheit by adding 40 to the number of chirps produced in 15 seconds by the snowy tree cricket common in the United States.

To hear the mating call of other crickets, a cricket has ears located on its knees, just below the joint of the front legs."
