Some scientists also think the amino acids that females receive on eating the males help them lay more eggs. This is because well-fed females seem to eat the males less than hungry ones. Some believe this helps the female get sustenance during the mating process, which can be very energy-intensive. There is no concrete reason for why Mantises do this.
