Daddy long legs, also known as pholcus phalangioides, are a type of spider that is commonly found in many parts of the world. These spiders are known for their long, thin legs and their ability to survive for extended periods without food. But just how long can a daddy long legs live without food? In this article, we will explore the answer to this question and delve into the fascinating world of these incredible arachnids.
Understanding the Biology of Daddy Long Legs
Before we can understand how long a daddy long legs can live without food, it’s essential to understand their biology. Daddy long legs are a type of spider that belongs to the family Pholcidae. They are characterized by their long, thin legs, which can grow up to 1.5 inches (3.8 cm) in length. These spiders are also known for their small body size, which is typically around 0.2 inches (5 mm) in length.
One of the most interesting things about daddy long legs is their unique physiology. These spiders have a slow metabolism, which means they don’t need to eat as often as other spiders. They also have a highly efficient digestive system, which allows them to extract as many nutrients as possible from their food.
The Importance of Food for Daddy Long Legs
While daddy long legs can survive for extended periods without food, they still need to eat to survive. These spiders are carnivores, which means they feed on other small insects and arachnids. They use their long legs to catch their prey, and their venomous fangs to kill and digest it.
Food is essential for daddy long legs because it provides them with the energy they need to survive. Without food, these spiders would eventually starve and die. However, as we will see, daddy long legs are incredibly resilient and can survive for a long time without food.
How Long Can a Daddy Long Legs Live Without Food?
So, just how long can a daddy long legs live without food? The answer to this question is impressive. According to some studies, daddy long legs can survive for up to 12 months without food. Yes, you read that right – 12 months!
This is because daddy long legs have a highly efficient metabolism that allows them to conserve energy. They can slow down their metabolism to conserve energy, which means they don’t need to eat as often. This adaptation is essential for their survival, as it allows them to survive during times of food scarcity.
Factors That Affect the Survival of Daddy Long Legs Without Food
While daddy long legs can survive for up to 12 months without food, there are several factors that can affect their survival. These include:
- Temperature: Temperature can have a significant impact on the survival of daddy long legs. These spiders are more active in warmer temperatures, which means they need to eat more often. In colder temperatures, they can survive for longer periods without food.
- Humidity: Humidity is another factor that can affect the survival of daddy long legs. These spiders thrive in humid environments, which means they need to eat more often. In dry environments, they can survive for longer periods without food.
- Age: The age of the spider can also affect its survival without food. Younger spiders need to eat more often than older spiders, which means they may not survive as long without food.
Other Interesting Facts About Daddy Long Legs
Daddy long legs are fascinating creatures that are full of surprises. Here are some other interesting facts about these spiders:
- They are not poisonous: Despite their fearsome appearance, daddy long legs are not poisonous. Their venom is not strong enough to harm humans, and they are generally harmless.
- They are excellent web-builders: Daddy long legs are skilled web-builders that use their webs to catch prey. They can build complex webs that are up to 3 feet (90 cm) in diameter.
- They are social spiders: Daddy long legs are social spiders that live in large colonies. They communicate with each other using vibrations in their webs.
Conclusion
In conclusion, daddy long legs are incredibly resilient spiders that can survive for extended periods without food. Their unique physiology and adaptations allow them to conserve energy and survive during times of food scarcity. While they can survive for up to 12 months without food, there are several factors that can affect their survival, including temperature, humidity, and age.
These fascinating creatures are full of surprises, and their ability to survive without food is just one of the many interesting things about them. Whether you’re an arachnophile or just someone who appreciates the natural world, daddy long legs are definitely worth learning more about.

How long can Daddy Long Legs survive without food?
Daddy Long Legs, also known as Pholcus phalangioides, are incredibly resilient when it comes to surviving without food. They can go for extended periods without eating, with some specimens reported to have survived for up to 12 months without food or water. This is due to their slow metabolism and ability to conserve energy.
Their ability to survive for so long without food is also attributed to their unique physiology. Daddy Long Legs have a low energy lifestyle, which means they don’t require a lot of energy to survive. They are also able to recycle their own waste products, which helps to conserve energy and extend their survival time.
What do Daddy Long Legs eat?
Daddy Long Legs are carnivorous spiders that feed on small insects, such as flies, mosquitoes, and moths. They are also known to eat other spiders and even their own kind. They use their long legs to capture their prey, and then wrap it in silk to immobilize it before feeding.
In captivity, Daddy Long Legs can be fed a diet of fruit flies or other small insects. They are not picky eaters and will consume whatever is available to them. However, it’s worth noting that they don’t need to eat frequently, and can survive for extended periods without food.
How do Daddy Long Legs conserve energy?
Daddy Long Legs conserve energy by having a slow metabolism and a low energy lifestyle. They are not active hunters and instead rely on their webs to capture prey. This means they don’t need to expend a lot of energy to catch their food. They also have a unique physiology that allows them to recycle their own waste products, which helps to conserve energy.
In addition to their slow metabolism, Daddy Long Legs also conserve energy by being sedentary for long periods. They will often sit in one spot for hours, waiting for prey to come to them, rather than actively searching for food. This helps to conserve energy and extend their survival time.
Can Daddy Long Legs survive without water?
Yes, Daddy Long Legs can survive without water for extended periods. They are able to conserve water by producing very dry feces and by being able to recycle their own waste products. This means they don’t need to drink water frequently, and can survive for long periods without it.
In fact, Daddy Long Legs are able to survive in very dry environments, and can even be found in deserts and other arid regions. This is due to their ability to conserve water and their low energy lifestyle, which means they don’t need to drink frequently.
How do Daddy Long Legs catch their prey?
Daddy Long Legs catch their prey using their webs. They spin a messy, irregular web that is designed to capture small insects. When an insect gets caught in the web, the Daddy Long Legs will feel the vibrations and come to investigate. They will then wrap the insect in silk to immobilize it before feeding.
Daddy Long Legs are also able to capture prey using their long legs. They will often sit in one spot, waiting for an insect to come close, and then quickly snatch it up with their legs. This method of hunting is less common, but can be effective for catching larger prey.
Are Daddy Long Legs poisonous?
No, Daddy Long Legs are not poisonous. They do have venom, but it is not strong enough to cause harm to humans. In fact, the venom of a Daddy Long Legs is so weak that it is not even capable of killing small insects. They use their venom to immobilize their prey, but it is not a threat to humans.
It’s worth noting that Daddy Long Legs are often feared due to their large size and intimidating appearance. However, they are harmless to humans and play an important role in the ecosystem by helping to control insect populations.
Can I keep Daddy Long Legs as pets?
Yes, it is possible to keep Daddy Long Legs as pets. However, they are not the most common or popular pet spider. They are relatively low maintenance, but do require a specialized enclosure and diet. They are also nocturnal, so they are most active at night, which can make them less interesting to observe.
If you are interested in keeping Daddy Long Legs as pets, it’s worth doing some research to learn more about their care and husbandry. They can be fascinating to observe, and can make interesting and unique pets for the right owner.
