How long does it take spider eggs to hatch?Eggs laid during a season with favorable weather (spring or summer) can hatch in a matter of weeks. Eggs laid in autumn will take several months to hatch, the eggs and spiderlings overwintering inside the cozy silken case.
How many eggs do spiders lay?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.
How long do the offsprings live with the parent?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.
Many species’ spiderlings hatch and simply fend for themselves. They either walk to new locations or travel by ballooning, a process whereby the tiny critters let loose a strand of silk that carry them miles away in the wind.
