Wolf Spider Babies( Care And Life Cycle Explained)

baby wolf spider

Wolf spider babies are an interesting parental care practice in which wolf spiders are unusual to most spider species. Wolf spiders are known for being the only type of spider that carries their egg sacs on their spinnerets or organs at the end of their abdomen. 

This is because after they hatch from egg sacs, these spiderlings climb up her mother’s legs and piggyback around with her to find food.

Wolf spider mothers dutifully carry their egg sacs on the spinnerets they call home, tirelessly weaving new silk as a pupae’s body grows. 

After an intricate and lengthy gestation process, the mother carefully carries her young one to freedom so it can break free from its chrysalis-like cocoon once more – only this time wrapped up with some mealworms! 

The newly hatched wolf spiderlings climb onto their mother’s back, where she piggybacks them around so that they may feast upon any juicy prey nearby.

Typically, female wolf spiders frequently walk around carrying their egg sacs than male Wolf spiders. The young spiders stay with the mother for 2-4 weeks after the eggs hatch before scattering. 

This post covers all you need to know about wolf spider infants, including how they are cared for by their mothers.

How Do Wolf Spiders Look After Their Young?

Wolf spiders’ maternal care seems to be more evolved than that of most other spider species. 

Most spiderlings, according to reports, exit the egg sac at night. Throughout the day, though, many observations were made. When exiting the sac, the first spider starts by piking its head out of the sac on any of the holes and then escapes out of the hole.

 It will then find an appropriate position on the back of the mother and will attach to it. 

Generally, the sac will be empty within three hours. The spiders will attach onto the mother’s back, and some even spill over to the sides as well as the thorax. 

Spiderlings stay with their mother, based on the species and time of the year, over a different length. This varies between 4 and to 50 days, depending on the type of the species.

According to research, spiderlings taken from their “mother’s” back have a greater mortality rate than those permitted to go naturally. Providing water to the babies when they’re on the “mother’s” back is part of parental care.

The creation, care, as well as perforation of the egg sac are the three different stages of maternal care provided by wolf spiders. A day before the occurrence, certain wolf spider species signal the beginning of egg formation.

Life Cycle Of Wolf Spiders

The woman’s wolf spider connects her pea sack to her spinners and has a regular life with the bag. When clutching her egg sac, she might show hostile behavior and persistently and horrifyingly seek it when removed from it. 

When the spiderlings get out of the case, they crawl into the abdomen and stay there till they are ready to find food for themselves for a maximum of two weeks or longer. For over 2 years, certain wolf spiders can live.

Women of different species create a light web over a drinking dish and a section of a cage floor. Real egg sac production starts when the female creates a circular mat parallel to the ground. 

The female swings her abdomen in an alternating manner in the clockwise direction as well as counterclockwise, creating her silk base with lengthy, burning strokes of the spinnerets. The mat’s depth is achieved by loops up and down with the tip of the abdomen. 

A number of small strokes up and down are used to complete mats and their edges until a rim forms, which gives the mat a nested form.

In the center of this mat, the female stops 3 to 4 minutes for her genital area. Then the egg weight and a liquid substance were placed. The egg mass is also covered by another short period of inactivity.

To protect the eggs, the female touches the edges of their spinners at the edge of the tube, heightens their body and with her spinners. 

The female may or may not touch their egg mass as they move their abdomen over the other side of the mat. so that they go back and forth in alternating clock and clock directions.

Once the eggs are thoroughly coated and the construction is further spun around the edge, the female releases the mat from the light web, That’s done by dragging her palpi over the wrapped egg mass as her chelicerae rip silk strands.

Females Wolf spiders push with their legs while tugging with their palpi exert more “freeing” power. When the sac is released, the third and first sets of legs are used to turn it, whereas the chelicerae and palpi are used to turn down the seam. 

To finish the very first phase of her mother’s care, she pushes and pulls the egg sac, which looks like a poached egg at this point, while rotating it with the third set of legs till it becomes practically spherical in form. 

Next, she uses her spinnerets to contact it. She goes away with the egg sac intact a couple of minutes later.

The second step of maternal care is the nurturing of the egg sac. A wolf spider’s “mother” would aggressively protect her egg sac from attackers. 

The egg sacs of “mother” lycosids are exposed to natural or artificial sunshine. Others are seen briefly soaking the egg sac in the water dish. “Mothers” that have highly infected or parasitized egg sacs have really been reported to destroy these eggs around the time they are due to hatch.

If they haven’t already done so after egg sac formation or soon after, females inside viable eggs destroy them subsequently. Several females have destroyed their egg sacs for unknown causes, or because they were deprived of an important nutrient in their diet, or because they were disturbed.

Wolf spiders, ‘mother,’ repair ripped or sliced areas in bags of egg. This allows an egg sack for the phase of its contents to be checked, returned to the “mother;” and, one or two days later, the same egg sack again – and if required, one or two days thereafter. 

That is especially helpful for the observer as spiderlings are kept one to three weeks after the egg hatch because, without that unintentional support from the ‘mother’ Spider, it is difficult to establish the exact incubation duration.

When the eggs start hatching, just little detectable movements, taken from the egg bag 20 to 30 minutes apart, may be seen with a microscope.

These movements can intensify until the eggs hatch after more than 6 hours. The time it takes to incubate an egg varies by species, ranging from 6 to 14 days. The time span between the hatching date within the egg sac and emergence is 4 to 22 days.

Entire days from egg sac creation to emergence can vary from 12 to 35 days, with the total time necessary for mothers to hold their egg sacs differing by species and season.

Feeding Wolf Spiderlings

If a wolf spider is pregnant and gives birth to her own brood of spiderlings, or baby spiders, she will feed them during the first few days of their existence. 

The wolf spider, unlike most other spiders, carries her freshly born offspring on her back. During this time, the infants usually survive on the remnants of the egg sacs in which they were carried. 

When the nursing phase is through, the mother wolf spider will go, leaving the young spiders to fend for themselves. Separate the young spiders from each other and at this stage to prevent them from eating on their siblings, and then offer them tiny food like fruit flies until they mature. They do not require as much food as mature spiders. Baby spiders may usually be fed once every five days.

How long do wolf spiders carry their babies on their back?

Wolf spiders are often confused with other species of spider, but they’re easy to identify. The most noticeable difference is that wolf spiders carry their young on their backs for a long time after the eggs have hatched. 

They can carry anywhere from 10-50 babies at a time. But, most of you have been wondering how long do wolf spiders carry their babies on their backs.

In general, Wolf spiders carry their babies on their back between 2-6 weeks. The spiderlings may be too small to hunt for food or fend for themselves. So, for two weeks they cling to their mother’s back and go through an intensive molt before finally deciding it’s time for them to strike out on their own.

Does the male or female wolf spider carry the babies?

The female wolf spider carries the babies. Male spiders are not involved in carrying eggs or feeding their offspring, and they often die after mating with females. Unlike Tarantula spiders, Wolf spiders have a more evolved maternal instinct than the later.

Females Wolf spiders produce up to 100 egg sacs that can contain anywhere from 20-2000 eggs each depending on how much food is available for them during development. 

Do baby wolf spiders eat their mother?

With so many mouths to feed and food scarce for new mother Wolf spiders, there have been rumors that baby wolf spiders eat their mother. As much as It is surprising that baby wolf spiders would eat their mother, recent research confirms.

In general, baby Wolf spiders eat their mothers. They tactically offer themselves to be cannibalized for the baby spider’s survival and it doesn’t seem like there are any negative effects on either party. 

The conclusion of my blog post would be “It turns out baby wolf spiders actually do eat their Wolf spider mothers.”


Wolf spider babies are first taken care of by the mother spider when they stay on the mother’s back for protection and feeding during the first weeks after hatching. A lot of processes are involved in the maternal care process, from sac creation to perforation of the sac.
