Yes, spiders lay eggs. After female spiders mate with males, they keep sperm in a holding place so they can fertilize the eggs. They fertilize the eggs right before laying them.
Most female spiders yield many eggs in order to make sure the species survives. Up to several hundred eggs are put in a sac. Females can create more than one sac but that differs based on the species.
Female spiders’ abdomens may expand due to a high amount of eggs, and their bodies contract after they lay the eggs. Spider eggs are laid during different times. For example, hobo spider females lay eggs in mid-September to October, but brown recluse spiders typically lay eggs between May and July.
Typically, spider eggs are contained in a silken sac, which guards the eggs from predators as well as changing temperatures. An egg sac can be larger than the actual spider. Spider egg sacs don’t all look alike - they may be flat or round or look like something else, and they can have varied colors such as brown or white.
The cocoon can be located in the soil, hang in a web, be held to a leaf, or can be found elsewhere. Long-bodied female cellar spiders usually transport their egg sacs between their jaws until the eggs hatch. Other spiders - like the wolf spider, for instance - also tote their egg sacs. Nursery-web spiders carry their egg sacs as well and create a spot for their egg sac to rest when the eggs are close to hatching. Spiders that yield multiple cocoons have an inclination to desert them.
