Spiders have babies by using the male’s sperm to fertilize the female. When the male and the female are ready to reproduce, the male will start to deposit his sperm into a small web. Then, the male will disperse his sperm on his pedipalps, approach the female, and insert the sperm into the hole on the rear of her abdomen.
Once the sperm is inside the female’s body, she will store the sperm inside her body near the ovaries. Months down the road, the female will be ready to lay her eggs. After she does that, she will use the stored sperm inside her body to fertilize the eggs. Then, small spiderlings will start to emerge from the eggs.
Do Spiders Have Sex?
Spiders don’t have sexual intercourse in the general meaning of the word. Instead, their process of creating eggs and fertilizing them is a little different.
The male will store sperm inside a web, which is where he’ll take it from when he feels like fertilizing a female. After that, he will approach the female and mount her. He will disperse sperm over his pedipalps; with his palps, he will then insert the sperm in the female’s body through the epigynum, which is the female’s genital structure for mating.
Once the sperm is inside the body, it will fertilize the eggs that the female lays. This will complete the process of fertilization, after which the eggs will be laid and some time will need to elapse for the eggs to fully mature.
The whole breeding process might take a few seconds up to a few minutes – with some spider species, this process might take up to a few hours, even.
In some species, this type of mating will result in the death of the male. For instance, male black widows will die after mating, while with other spider species, the female might consume the male spider after this process. This is especially true when they mate with males that are smaller than the female.
Where Do Spiders Lay Eggs?
Spiders will lay eggs into the spider egg sac, which is created by the female to protect the eggs from predators and other spiders.
The egg sac will be made from thick, protective silk, which should be thick enough to stop the predators from accessing the eggs. The female will create this sac right after she has received the sperm from the male.
Some spiders don’t create sacs to protect their eggs. Instead, they will stand around the eggs constantly, trying to protect the eggs from predators constantly until they hatch. This is particularly true for the spiders that don’t tend to create elaborate webs and rely on ambushing to catch their prey.
What Happens with the Eggs?
After the female has successfully received the sperm from the male, she will use the sperm to fertilize her eggs and then lay them. Most spider species will lay the eggs inside a silk encasement to protect the eggs from predators, while other species will guard the eggs all the time.
Spider eggs will usually hatch in about 2-3 weeks, depending on the species, time of year, and the number of eggs there are to be hatched. A female will normally release hundreds to thousands of eggs at the same time.
After the spiderlings emerge from the eggs and they hatch successfully, they will be guarded over closely by their mothers (or fathers). Some spiders, like the wolf spider, will carry their babies around for the first few weeks, until the spiderlings can take care of themselves completely.
The spiderlings will then take a few weeks to grow up and be able to take care of themselves. They will go through several periods of molting during the first few weeks of their lives, which allows them to grow quickly and adapt to their surroundings.
The small spiders will be checked by the parents for the first few weeks until they’re fully sexually mature. After that, the whole breeding cycle will repeat when the males start developing their own sperm and start seeking their partners for breeding.

When Are Spiders Mature for Mating?
It will take between 5 to 10 molts for the spider to be completely adult and be able to breed, which can take several weeks to several months, depending on the species of the spider.
How long the spider will survive after that will also depend on the type of the spider. Some spiders die when mating, which means their life expectancy will be only 1-2 years. Other spiders survive even when mating and might go through several cycles of mating in their lives, and perhaps even reaching a ripe old age of 20.
For the male spider to be completely sexually mature, he will need to be larger than the female, strong enough to mount her, and also mature enough to produce sperm so that he can then breed.
Females, on the other hand, might become sexually mature slightly earlier than males. This will depend on the species of the spider and the size of the female. It will depend on when the ovaries in the female become receptive to the sperm of the male – this might also take a few months after the spider has been hatched.
Some spiders mate for life, while others only mate once and they die – this is especially true of the males. Females, on the other hand, might breed several times in their lifetime.

Conclusion
The spider breeding process is slightly different from the process that we know. They don’t reproduce with the same sexual processes as humans do – instead, the male will insert the sperm inside the female with his pedipalps.
After that, the female will start laying eggs and with the help of the sperm she’s received, she’ll fertilize them. After a few weeks, small spiders will start to emerge from these small eggs.
This process will repeat in a cycle, as long as the eggs are protected adequately and the spiders grow up old enough to mate.
