Spiders eat twice as much animal prey as humans do in a year

David E. Hill/Peckham Society/PA Wire

Most of their victims are insects but the largest tropical species occasionally make a meal of vertebrates such as frogs, lizards, fish and small mammals.

There are more than 45,000 species of spider living in all parts of the world with a collective weight of about 25 million tonnes.

Together they kill between 400 million and 800 million tonnes of prey annually, a team of Swiss and Swedish scientists has calculated.

In comparison, all the humans on Earth consume about 400 million tonnes of meat and fish each year, according to the United Nations Food and Agriculture Organisation.

The appetite of spiders even exceeds that of whales, which get through an estimated 280 million to 500 million tons of prey a year.

“Our calculations let us quantify for the first time on a global scale that spiders are major natural enemies of insects,” says Martin Nyffeler, from the University of Basel in Switzerland. “In concert with other insectivorous animals such as ants and birds, they help to reduce the population densities of insects significantly.”

“Spiders thus make an essential contribution to maintaining the ecological balance of nature,” Nyffeler says.

Ninety per cent of spider prey consists of insects and springtails, small insect-like arthropods. The team showed that spiders killed many times more insects in forests and grasslands than in other habitats.

Their impact was lower in agricultural areas because intensively managed farmland is not favourable to spiders, the researchers said.

“We hope that these estimates and their significant magnitude raise public awareness and increase the level of appreciation for the important global role of spiders in terrestrial food webs,” says Nyffeler.

The food source for spiders depends on the species. Most spiders are predators feeding on insects and even other spiders. It’s important to know that most spiders will only feed on live prey or prey that they have recently killed.

What’s on the menu?

Spiders are known to eat a variety of foods. Web-building spiders commonly consume flying insects such as flies, mosquitoes, moths and butterflies. Hunting spiders, as their name implies, lie in concealed areas and attack their prey as it comes near, while other spiders are fast enough to run down, capture and eat insects such as crickets, grasshoppers and beetles.

What do spiders eat other than bugs?

Although most types of spiders do not eat plant foods, there are a few species that will feed on materials derived from plant life. In the jumping spider group, there is one species that gets 90 percent of its nutrients from the leaves of the Acacia tree, found primarily in Central America. There is also a species of water spiders that constructs its web under water. The primary food of choice for this spider is fish.

Now that you know you’re not part of the food chain for spiders, that doesn’t mean you have to tolerate them invading your space. If spiders are a problem, call the pest management professionals at Terminix® for the best solution.

How to Identify a Fire Ant Mound

Fire ants are more than just annoying insects that may leave itchy stings—they can also be destructive. The red-imported fire ant, often referred to as RIFA, is an invasive species and has been known to prey on other native insect species as well as plants, with some fire ants even preying on small mammals many times their own size. Their invasive and destructive behaviors are why it’s important to know how to recognize both the ants themselves and where they reside.

Why Are Bees Important?

You’ve probably heard the phrase “Save the bees” in the last few years. But you might not know why it’s a detriment that our bee population is in danger—or why bees are so important in the first place. Bees are small after all, most around half an inch in size.

What Do Spiders Eat?

Spiders are part of a group called arachnids and are found in most places on Earth, except Antarctica. They have eight legs and two body parts: the cephalothorax and abdomen. There are thousands of spider species and their diet varies widely, largely dependent on their environment and size. For simplicity, we will generalize the diet of these species, but note that this generalization might not be fully accurate for all spider species. That being said, studies thus far on spiders have shown that the majority of species have similar dietary and digestive mechanisms with just a few variations based on the environments in which they live.

Spider Diet

So, what do spiders like to eat? Thanks to Hollywood movies, many of us suffer from paranoia of getting bitten by a spider and dying some tragic death wrapped in a web. However, it’s important to note that humans are not a food source for these diminutive eight-legged creatures. With that being said, let’s now look into more detail about the preferred food choices of spiders.

The diet of a spider depends on its type. Web-building spiders like to feed on insects like flies, moths, mosquitoes, etc. Hunting spiders are a more voracious variety of spiders. They camouflage themselves and attack their prey when it’s in their proximity. They eat grasshoppers, beetles, crickets etc. Some giant hunter species like the huntsman spider are reported to even feed on lizards and frogs. It must be noted that most spiders like to feed on live prey or prey that has been killed or died recently. Stale prey is a big turn-off for these diminutive arachnids!

Spiders don’t usually dine on plants and cannot eat solid food directly. They need to liquify their food before ingesting it, and their digestive system is not designed to digest the cellulose of plants. Recently, however, a spider species called Bagheera kiplingi was discovered in Central America whose primary food source is plant material! This plant-eating spider species dwell on the Acacia tree and feeds on the nectar the tree provides. The digestive system of these spiders can process sugar, proteins and even some fats, but whether or not they can digest cellulose remains a matter of further investigation and studies.

Some spiders can be described as ‘fussy eaters’, as they are very selective and only confine their diet to a particular type of prey. For example, Lampona, a white-tailed spider, only prefers to eat other spiders. They rarely go beyond foraging for insects other than spiders. Lampona are sometimes even successful in trapping elusive long-legged spiders like Pholcus.

Interestingly, many spiders in the Myrmachne genus, such as the Kerengga spider, deceptively mimic ants and prefer to feed on them once the right opportunity presents itself. They have adapted themselves to look very similar to an ant, which often gives them access to the foraging ant’s stream without alarming the colony. Ordgarius magnificus, commonly called the magnificent spider in Australia, uses a different means of disguise to prey on ants. They suspend a fluid droplet containing a powerful pheromone attractant that draws insects like ants and moths toward the droplet. When the poor prey fall for this droplet trick, the magnificent spider attacks and eats them.

Cannibalism

Although spiders are generally solitary creatures, if two disparate species move into close proximity, the more voracious of the two may cannibalize the other.

While female spiders do display usual maternal behavior towards their newly hatched spiderlings, it is not uncommon that a spider mother may also eat her newborns if there is an acute shortage of food. Not only mothers, but also siblings will eat their newborn kin in adverse circumstances.

Water

We studied a great deal about what spiders eat, but what about their drinking needs? Well, spiders generally don’t need to drink water as frequently as humans do. Their water source is usually derived from their prey itself. Water is also produced as a byproduct of their metabolism.

Despite this conservative behavior in terms of water, some spiders do run the risk of desiccation; particularly those belonging to mygalomorph species. In fact, female mygalomorphs spend most of their lives in a burrow where humidity levels remain high. Adult male mygalomorphs come out of the burrow in the night when humidity is also high or in the day during the rainy season. Funnel-web spiders are so fond of moisture that they are often spotted near swimming pools or leaky garden taps.

How Often Do Spiders Eat?

The eating regime of spiders largely depends on the availability and type of prey in the vicinity. Unlike humans, spiders do not opt for a three-meal-a-day dietary routine! They are opportunistic feeders who prey on insects as soon as they come close to it. After gobbling in a good amount of prey, they might not need to look for more food for a few weeks. Thanks to their poikilothermic nature, they can manage to survive the temporary unavailability of food resources. However, a prolonged period of starvation, further worsened by unsuitable weather, may lead to the spider’s death.

Can spiders hibernate? Yes, but only to a small extent. Those who live through several cold months are effectively in a hibernation state, as they seem to survive without any food intake and limited internal fuel reserves.

Spiders are some of the most fascinating creatures in nature, so it’s not surprising that we have countless portrayals of spiders in popular culture. The dietary and eating patterns of spiders that we discussed are based on what has been observed and recorded through studies and research projects around the world. Even so, there is a very good possibility that there are some exotic spider species with eccentric eating habits that have yet to be discovered!
