EGGS TO BABY

Once the eggs are fertilized and the eggs are matured, the female lays her eggs. The mother has to take care of her unborn children because the elements, predators or parasites can harm them. The Scytodes and the Pholcus (daddy longleg) use the simplest form. They carry their children in loose bundles with them. They can do that because they live indoors and are not threatened by the weather. Other species like the wolf spiders put their eggs in a sac of silk and attach the sac behind their body. After their children are born, the female carries them for a while on her abdomen.
Many other species put their eggs in a sac of silk and guard them until the youngsters emerge. Often she will care for her youngsters until she dies. Among some species, the children eat the mother. Some Araneidae guard their eggs until the mother dies in the autumn. The eggs stay unattended until they hatch the following spring.
