SHE EATS HER OWN INFERTILE EGGS In a little more than an hour the spider devoured about 300 eggs. When she had finished her repast, the spider appeared no larger than she did before commencing, even though the egg mass was the size of her abdomen. About half of the uneaten eggs had fallen from the sac and lay at the bottom of the burrow when this photograph was made.
