The brown hermit spider is a small, dark spider that can often be found living in abandoned buildings or apartments. They are shy and retiring spiders that usually only come out at night.

The life cycle of the smallest spider in the world

As with any animal, spiders will go through different stages of their life cycle. Below is the basic life cycle of a spider. Their life occurs in four parts:


The females retain the spermatophores within them after mating is complete until they are prepared to deposit their eggs. The female spider may deposit only a few eggs or thousands, depending on the species. Each egg will initially be encased in a silk sac unique to it.

Egg Sac

All of the eggs are kept and safeguarded in this location until they are ready to hatch. A bigger egg sack that encloses each individual egg will thereafter be made by the mother spider.

The eggs will remain together in this bigger sac, which will also shield them from the environment and any predators.

While some spider species will keep the egg sac in a secure spot, certain species may carry the egg sac on their backs.

The eggs will start to hatch after a few weeks.


These seem to be little versions of the adult spider. The juveniles will start moving as soon as they leave the egg sac for the first time. Others may “fly” away on their silk, while other species will only scurry away. Up until they reach maturity, they will have 5–10 molts.


Spiders are one of the many adult animals that can be found on this planet. They come in a variety of shapes and sizes, with some being considerably smaller than others.

Adult spiders are ready to mate and have babies. In order to b able to mate, the male spider must find a female spider. After mating, the female spider will lay eggs which will hatch into baby spiders.

Baby spiders will go through a growth phase before becoming adults. Spiders have a cycle of life where they grow, mate, and die.

Smallest spider in the world’s Natural Predators

Despite being predators in and of themselves, many spiders are relatively few. There are several animals that like feasting on little creatures like spiders and insects. Some of the most frequent spider predators are listed below:


Lizards are known to eat spiders and other small invertebrates. This makes them a natural predator of spiders and can help keep their populations in check.


Birds love to eat spiders of all kinds. In the United States, robins and wrens are the two birds that most frequently make a meal of spiders, especially the smaller ones.

Tarantula Hawks

They are a kind of wasp that preys on spiders. They are known for their large size and painful sting.

They use a loud noise to lure the spiders out of their holes and then sting them. Once they have paralyzed the spider, they will carry it back to their nest to feed their young.

The hawk has a stinger that can paralyze the small spiders, and it then liquefies its prey with enzymes.


Hopefully, now you know all about the smallest spiders in the world and will be able to recognize one if you see one. However, make sure to keep your distance either way.
