If you’ve ever wondered what a spider eats, you’ve come to the right place. These spiders don’t just go after bugs. In fact, they don’t even immediately eat the flies they catch. Instead, they will wrap the flies in a silk web and hang them on their web to preserve them.

Pollen
Until recently, it was unknown how much pollen spiders ate, but recent studies have shown that spiders actually eat pollen from various plants. The grains are too large for spiders to accidentally swallow, so they suck them up instead, where they dissolve the outer coating and draw in the nutrients. These results support the view that spiders are omnivores, as pollen is an essential part of the diet of many insects, including spiders.
Honeydew
Honeydew is a liquid excretion produced by insects that feed on tree sap. It is clear, sticky and rich in sugar. In addition to honeybees, yellow jackets and butterflies have been observed to gather honeydew from trees and shrubs. If you’ve ever watched a bee, you know that they love to collect this sticky substance.
Nectar
Spiders feed on a variety of plant products, including nectar. The largest family of spiders, jumping spiders, have been observed feeding on plants in every continent except Antarctica, with leafy greens being the exception. Twenty to thirty percent of all jumping spiders have fructose in their guts.
House flies
House flies are what spiders primarily eat, but they’re not the only thing spiders eat. They also eat other types of insects, including wasps and beetles. As a result, these insects can be considered a source of protein. Fortunately, a variety of different insects and spiders can provide these animals with a variety of nutrients.
Cockroaches
Some spider species are specifically designed to feed on cockroaches. The American house spider, the huntsman spider, and the jumping spider are all known to feed on cockroaches. Cockroaches are also eaten by the brown recluse spider and the widow spider.
Birds
Blackbirds and other birds eat spiders, especially young ones. Birds are opportunistic hunters and feed on terrestrial spiders because they are high in protein. Blackbirds can be found everywhere, but they are most likely to be found in gardens and wooded areas. In addition to eating spiders, birds also eat other insects.
Lizards
Spiders will eat lizards, according to a recent study. However, such predation of lizards is rare. We found only five reports of spiders preying on lizards. One of the reports was from Central Chile, where a Liolaemus lemniscatus (Gravenhorst, 1838) was observed approaching a Grammostola rosea (Walckenaer, 1837) which was hidden in a burrow. The predator sunk its fangs into the prey’s neck and dragged it into the burrow. The whole event lasted around 90 seconds.
Small mammals
Spiders are notoriously voracious predators, eating as much as 400 to 800 million pounds of prey every year. This amount of food would equal about half of the amount of meat and fish that human beings eat each year.
Ants
Ants are an important part of the ecosystem and are an important source of protein. They get this protein from a variety of sources, including dead insects and plant matter. They can also detect different types of chemicals, including proteins and sugars, thanks to their chemosenses. In addition, ants have tiny bristles on their bodies that act as olfactory receptors. When they come into contact with these substances, they produce a scent called pheromones that attract other ants.
