Scorpions are carnivores and feed on crickets.
Feed them two crickets per week. There should be no more than two crickets in the cage at any one time or else the scorpion will be stressed by constant movement of crickets. The male will look for a smooth surface on which to deposit his sperm. Once the sperm is deposited, he will pull the female over the sperm. The female will lower herself over the sperm and transfer it through her genital opening.
