He has to give the right message or he will become a meal instead of a mate. If the female likes the message, she will allow him to mate. A fter the spiders have mated, the female will lay her egg case. Depending on the species, the egg case may hold hundreds of eggs, or just a few. The egg case may be wrapped with very tough silk or barely at all.
Some spiders die after laying the eggs.
Others take good care of the eggs and protect them from enemies. Wolf spiders carry the egg case around with them attached to the spinnerets. Once the spiderlings hatch, they usually stay in a tight group for a while, then they will disperse. S piderlings can fly on a strand of their own silk picked up by air currents. This is called ballooning.
