Our friend Jeremiah gave some praying mantises to us today. He dropped them off at our house because he had too many. He got an egg sac and an egg sac can have up to 100 eggs in it. We got 15 mantises and a lot of fruit flies for them to eat. I wanted them because I like to study insects. I hope that they will live to get big and green. Right now they are about half an inch long, but they get to be 2 - 2 1/2 inches.
