The difference between a male and female cricket is the points on their rump. A female cricket has two outer softer points on her rump and one is the middle that has a little bit of black on it. The reason for the middle one is for distributing eggs into the soil once she mates. The male crickets have only the two outer softer points. Also, some people think that the female chirps higher and the male chirps lower. That is not true. The females chirp very softly at night which makes it hard for the human ear to hear.
