Why Do Spiders Die After Giving Birth?


In this blog post, we will be discussing about baby spiderse in great detail and start off by answering the question “What Do Baby Spiders Eat When They Hatch?”. Spiders are really fascinating and interesting creatures. You might hate them or they may disgust you but you cannot refuse to believe how impressive these little monsters are!

Spiders are the most widely inhabited anthropods which mean they are not in anyway insects. Yes, you heard that right spiders are not insects. So why are you reading this blogpost under the name “Insect101” because spiders are commonly perceived as insects and leaving behind our favorite and coolest crawling creep would be such a loss!

Coming back to the main crux of this artile, let’s start off by answering “Why Do Spiders Die After Giving Birth?”

Spiders die soon after giving birth to hundreds of eggs because it takes too much strength from them, is too exhaustive a task and spiders mostly are malnourished while going through of giving birth. Birthing in spiders is a task that means making egg sacs along with laying eggs within them. This is not an easy task and can even take days. Moreover, pregnant spiders have to produce hundreds of babies and sometimes nearly a 1000 babies , this is without a doubt something that requires quite a lot of strength as well as energy and sometimes even more then what they have in them, and that is why they end up dying after exhausting theirselves for days on end.

Another very important point to note at this point whilst on this topic is that not all spiders die right after laying eggs and putting them in the egg sacs, in fact some of them do survive to live onwards and live by their days, but giving birth in itself is so exhaustive a task that it ends up taking life out of many of the new mothers, especially if they do not have a good food source and are already week

Process of Giving Birth In Spiders

Pregnant spiders give birth by laying eggs and as they have to lay quite a few babies, they form separate egg sacs which contains from a few to a hundreds of eggs that will then go on to hatch after 2 to 3 weeks varying depending on the species of the spider in question

Building these egg sacs along with laying the eggs within is a very exhaustive and long process. Some spider mothers also carry the egg sac along with them wherever they go, others wait for the babies to come out and some just go after laying them.

Do Baby Spiders Stay With Their Mother?

No, Not for long, they roam near the nest for the first few weeks of being born if possible, but they usually do not stay with their mothers at least not for long. But there are some species ( social spiders ) that live in a colony together and harmoniously with their parents, siblings as well other spiders from the species. There are also some other species of spiders that take care of their children for 2 to 3 weeks after they are born and then let them go, but most commonly this is also a behaviour that is not usually observed

Most commonly the social behviours of spiders have been caterogorized into 6 main categories and it is estimated that spiders as anthropod have evolved nearly 19 times when it comes to their social aspects of life. Most of the 6 categories of social behavior of social spiders include spiders using the same nest, copulate each other and provide food if possible

Moving on into a bit more depth into the social life of spiders, the level of sociality can vary quite a bit within a single specie of a spider as well as you might have guessed. This is mostly due to the differnet environments that they are sorounded and the things they are bound to do for survival. These adaptations that they embed into their lifestyles help them survive better.

One of the most social spiders’ species are Anelosimus eximius. They are quite often found working and living together. Moreover they have often also been seen making webs of over 25 feet long and even have upto 50,000 spiders living in their colonies, yea that’s right, over 50,000 spiders living together

Do Baby Spiders Eat Their Mother?

Yes though not common in all species and mostly only seen in some colonies, it is common for baby spiders to eat their mothers, Sewlal , a researcher on this very subject says the following “While it may seem unthinkable for a child to cannibalize its mother, it’s important to understand matriphagy has evolved over many generations to be the most effective means of ensuring the survival of the species.”. But like we mentioned taking the overall population of the spider-verse this is not that common as many of the spiders do not live in colonies to start with and this has been seen in only a few spider colonies. One of the spider species where baby spiders have been seen eating their mothers is Stegodyphus lineatus.

Do Baby Spiders Make Webs?

Yes, baby spiders do make webs but they are not as big as the adult spiders. Moreover, the amount of web as well as when they start producing webs depends very much on the species of the spider being talked about. So yes starting off the bat, baby spiders make webs and try to catch their, usually small prey. Some baby spiders have been observed to make their first webs only a few hours after they have been born as this is something that they are born with and know how to do instinctively just like walking and eating
