Spiders are incredibly fascinating creatures that come in a wide variety of shapes and sizes. While many people think of spiders as strictly nocturnal, they can actually be active during the day or night.

Some species of spiders are more likely to be active at night, while others are more active during the day. Whether or not a spider is active at night often depends on its environment and what it is hunting for.

Therefore, this brings up the inevitable question-Are spiders nocturnal? or is it otherwise?

Let’s Find out!

Are spiders nocturnal?

The simple answer to are spiders nocturnal is yes. 

According to the studies, spiders are generally nocturnal animals, meaning they prefer to hunt and move around at night. 

Are spiders nocturnal

This is because there is less competition for food and prey during the night, as well as cooler temperatures.

Furthermore, nocturnal spiders have adapted to rely on their senses to stay hidden and hunt successfully during this time of day; they typically have better vision and a heightened sense of smell.

However, it is important to note that nocturnal activeness varies with species. Not every spider is nocturnal.

While some spiders are entirely nocturnal, sleeping during the day and hunting at night, others may be active throughout the day or show dynamic behavior only during the day. 

What time of the Year are the Spiders most Active?

In the early winter and late fall, spider activity is at its peak. This is because they are preparing for their winter hibernation

In fact, these critters become more visible during this time as they search for food and mates.

Unfortunately, this is also the worst time for spiders as they target our homes for their cozy climate.

Do Nocturnal Spiders Nap During the Day?

Since nocturnal spiders are more active at night, they spend the majority of the day sleeping or relaxing.

In fact, the majority of the spider species do the same.

The nocturnal species tend to take short naps during the day to replenish their energy so they can expend a lot of it while hunting at night.

Why Are Spiders More Active at Night?

Spiders are more active at night because they avoid predators during the day. This additionally assists them in moving around and hunting easily without having to worry about being eaten.

Therefore, you’re more likely to see spiders at night than during the day!

Do Spiders Have Good Eyesight to facilitate a nocturnal lifestyle?

Spiders have good eyesight due to their multiple eye sets. They typically have two to eight eyes, depending on the species. This allows them to see in a variety of light levels and environments.

However, good eyesight is not their primary sense for a nocturnal lifestyle. These critters depend on other senses, such as touch and smell, to move around, detect movement and hunt for their food.

Where Do Nocturnal Spiders Hide During The Day?

Generally speaking, nocturnal spiders can be found both indoors and outdoors. These critters are usually shy and will try to avoid contact with humans.

As for their location during the day, they like to hide in dark, secluded areas such as under rocks, in crevices, corners of rooms, under furniture, or in woodpiles.

For instance, take the orb weavers; these nocturnal spiders can be seen hanging in their cozy webs in dark, isolated areas. Other spiders, such as jumping spiders, like to hide under leaves or inside crevices on plants.

Some Common Nocturnal Spiders

Most spiders are nocturnal, which implies they usually surface at night. The most prevalent and well-known spiders falling under the category of nocturnal species are enlisted below:


Tarantulas can be located all over the world and come in a range of sizes and shapes. They are typically shy creatures that prefer to stay in the shadows.

In fact, exhibiting nocturnal behavior, tarantulas are generally active at night, as they need to hunt for food and find a mate.

That said, Tarantulas can be beneficial to humans as they help keep down the population of other pests.

These spiders only bite humans if they feel threatened; most of the time, their bites aren’t harmful.

Orb-Weaving Spiders

Orb-weaving spiders are the most common type of spider in North America. They get their name from the fact that they build webs that look like orbs.

These spiders are active at night, and you can often find them hanging upside down, centrally in their webs, waiting for prey to stumble in.

Black Widows

Black widows are spiders that are typically considered to be nocturnal. This means they are more active at night than during the day.

What’s more, these nocturnal spiders are one of the most feared spiders in the world. They are known for their black color, toxic venom, and webs often found in dark, secluded areas.

Wolf Spiders

Wolf spiders are another common spiders that are active at night. This is because they have reflective eyes, which help them see in the dark.

They are also generally considered to be more aggressive than other spider species.

Brown Recluses

Brown Recluses are spiders that live in the dark and are feared for their venom. They are primarily nocturnal. In fact, nocturnal pests are used synonymously with the brown recluse.

Brown Recluses are shy and generally avoid humans, but they can bite if they feel threatened. The bites of Brown Recluses can be dangerous.

Common House Spiders

House spiders are the most common type of spider found in homes.

This spider is more active at night because that is when they hunt for prey. 

Although they are typically not thought of as pests, they can be an issue if they create their webs in places where people congregate.

Are Some Spiders Diurnal?

There are a number of spider species that have evolved to be diurnal, meaning they are active during the day. This characteristic is in contrast to most spiders, which are nocturnal and only active at night.

There are numerous factors that can influence whether or not a spider becomes diurnal, including their environment and the availability of food.

One of the most common examples of diurnal spiders is the Jumping spider.

Difference Between Nocturnal and Diurnal Spiders

There are many other differences between nocturnal and diurnal spiders. For example, nocturnal spiders are typically smaller in size than their diurnal counterparts.

Nocturnal spiders also tend to be more aggressive and territorial, as they have to compete for food and resources during the night.

Furthermore, nocturnal spiders typically have better vision in low-light conditions and use their sense of touch to find prey. On the other hand, diurnal spiders have good vision during the day and use their web to trap prey.


In conclusion, spider species come in nocturnal and diurnal categories. However, according to studies, most spiders are nocturnal. This means they are active when it is dark and tend to be more secretive. Nocturnal spiders typically have better eyesight and hunting skills than their diurnal counterparts.
