If you want to know what animals and plants spiders eat, you’ve come to the right place. Here’s a look at their food chain, including insects, reptiles, fish, and centipedes. The smallest spiders can do just as much as the largest ones. Despite their tiny size, spiders perform remarkably complex tasks. The smallest spiders can even do as much as larger ones.

Insects
A major part of the spider food chain is insects. Spiders, like other spiders, consume insects as part of their diet. Some spiders intentionally eat plant material, like seeds and pollen, while others feed on insect-eating plants. However, for most spiders, meat is essential for nutrition and growth. The spiders’ main prey is the acacia tree, a shrub with yellow or white flowers that grows in warm climates. The acacia plant is often covered with thorns. Insects are part of the spider food chain.
A British scientist estimated in 1947 that there were at least 2.2 trillion spiders in England and Wales. Insects are intimidated by spiders and eat less in the presence of the predators. This study was conducted by Klaus Birkhofer, Martin Nyffeler, and Michael Bates of the University of Basel in Switzerland, the Lund University in Sweden, and Brandenburg University of Technology Cottbus-Senftenberg in Germany. The study is published in the Springer journal The Science of Nature.
Reptiles
A variety of reptiles feed on spider eggs, which provide highly nutritious food for their larvae. Other animals, such as wasps and flies, use their long ovipositers to penetrate the egg sacs. Mantispid lacewings lay their eggs on tree bark, and the larvae then disperse to the crevices in search of spider egg sacs. Some spiders also become victims of fungal and worm infections.
While most snakes have venom potent enough to defeat a spider in just a few minutes, some spiders take days or weeks to kill their prey. This irregular feeding pattern allows spiders to feed in excess when food is plentiful and to store it as energy reserves. Although most snakes have poisonous venom, spiders do not use their venom on soft body parts. Instead, they suck the snake’s soup into their digestive tract.
Fish
Spiders, like all vertebrate animals, must eat something to survive, and this includes fish. Spiders often prey on aquatic insects, such as tadpoles, but fish are also an important part of their diet. The average size of a fish is about twice as large as a spider, so a spider may eat up to 30 grams of fish in one day. In addition to fish, spiders may eat a variety of other insects, too.
It is unclear how much fish spiders eat, but the mass of their muscle tissue is similar to that of their insect prey. This makes fish an important source of protein for spiders, as well as a better meal than insects. The spiders’ large chelicerae may also be a reason for this behavior, but more research is needed to find out the exact reasons why fish are so valuable to spiders.
Centipedes
Centipedes are the primary prey of many spiders. They can reach a length of one and a half inches and are greyish-brown in color. House centipedes are mostly found in bathrooms, basements, crawl spaces and damp closets. The presence of centipedes in a home may indicate a larger infestation of spiders. Although not a serious pest problem, these creatures are an important part of the spider food chain.
The role of centipedes in the spider food chain is complex. Centipedes are important feeders for spiders, as they provide food to other insects. Centipedes lay 10 to 60 eggs, which develop for several months. Young centipedes have fewer leg pairs than adult centipedes. They grow faster and add leg pairs with each molt. Centipedes may live up to seven years.
Fishing spiders
You’ve probably seen fishing spiders while out on the lake, but did you know that they are also a part of the spider food chain? These spiders are a common sight, and are beneficial in the ecosystem. They are excellent pest control, eating many different insects. While they may be found near lakes, streams, and ponds, the dark fishing spider can also be found in dry wooded areas. You can find these critters under stones in a garden or inside mulch.
Like many spiders, fishing aphids are not harmful to humans, but can be a nuisance to humans. You can remove them from standing water by scooping them up and releasing them from your home. If you’re concerned that you’re attracting them indoors, clean up any water on your floors, walls, and windows to remove their food source. If you’re worried that you’ll have a fishing spider infestation in your home, release them into a jar.
Tarantula Hawk
The Tarantula Hawk and spider food chain can be easily identified if you have seen either. This predatory spider is capable of killing wasps and other small insects. Its jaws and beak are too strong for wasps, and so the tarantula hawk stung them. The sting rendered them incapacitated within 1.5 to 2 seconds. They then drag their prey over the ground to the nest burrow.
The tarantula hawk has long, curved, and sharp stings. The venom is not meant to kill but to paralyze the prey. The female tarantula hawk then drags its immobilized prey into her brooding tunnel. Once inside, she covers the entrance with her curved sting. She then waits for her egg or wasp larva to hatch.
