Black widow spider with its eggs
Seven days after mating, the female lays a number of 2000 eggs. These eggs have the appearance of jelly capsules of a transparent white, which are protected and separated in different sacks all over the web.
In a month or so, the baby spiders grow and tear the sacks, getting away from their mother to start their own arachnid lives. They are so small that they can make use of air currents in order to travel away.
A black widow spider usually lives for three years.
