Female spiders are fairly prolific at generating offspring, some creating several egg sacs with dozens of eggs in each. Most web-building spiders favor this strategy, knowing that only a few of their offspring will survive to adulthood. Some egg sacs, such as those of Argiope, can have up to 1,500 eggs each. Tiny spiders, such as some Erigone, may build egg sacs with as few as 10 eggs. Hunting spiders tend to have fewer offspring, but protect them better. Female wolf spiders carry their egg sacs with them, attached to the spinnerets. Once the spiderlings hatch, mother wolf spider lets them ride on top of her abdomen until they have their first molt, at which point they disperse to fend for themselves.
