The young spiders are called spiderlings and are hatched from eggs. The eggs are in a baglike structure wrapped together in a membranous pouch. The sac may be carried around under the female spider or hid in an out of the way place. The spiderlings are duplicates of the adults and grow by a procession of exfoliation. Surprisingly, spiders can live up to 2 years.
Spiders create and use silk.
Located at the pinnacle of the abdomen is a collection of glands from which silk is produced as a liquid that solidifies to air exposure. The silk is used to catch prey, build cover, to assemble the web sac, and as leverage. Spiders can be advantageous to man in that they help to control the insect population. Spiders are non-aggressive and would rather flee from man. They are shy and would rather hide from human beings.
