Whether a person thinks they are fascinating wonders of evolution or are so creepy that they cannot be in the same room with one of them, spiders are an invaluable part of any ecosystem. They keep nature in balance by devouring insects, including what people consider to be pests, the number of which could otherwise be enormous. In turn, they are food for other predators, in some cases including humans.
Spiders are found all over the world except Antarctica. There are about 50,000 species that belong to 129 families. Although some people think so, spiders are not insects, although both animals are arthropods. They are arachnids, which means they have four pairs of legs, they do not have wings or antennae, and they have two rather than three body parts that insects have. These body parts are the cephalothorax and abdomen.
There are spinnerets on the abdomen that produce silk, although not all spiders weave webs. Like insects, they have jaws, but most spiders have jaws. These fangs deliver poison. The venom of most spiders is not dangerous to humans, but they paralyze very well and partially digest their prey. Read on to find out what’s on the spider diet.
What food do spiders eat?
First, not all spiders are strict predators. Beautiful green, gold and red stripes Bagheera kiplings from Central America eats structures called Beltian bodies from acacia trees. They also eat nectar and ant larvae, and if they are really hungry, they eat each other. Though Bagheera kiplings was described in 1896, scientists still do not know how it feeds on Beltian bodies, rich in proteins and fats.
Other spiders eat nectar, seeds, pollen, honeydew, leaf material, silk from their nets, and dead arthropods. Like other animals that molt, many species eat their exoskeleton. These food products give the spider a respite from the need to hunt and subdue sometimes dangerous prey. They also do not force the animal to expend energy for the production of poison and silk.
Spiders get an amazing variety of animals from their predators. They are not all unfortunate insects! Here’s a list.
Of course, lizards and other vertebrates are caught by large spiders and probably infrequently. Even the Goliath tarantula spider doesn’t eat birds all the time. Its usual diet consists of worms and larger insects, frogs and toads, snakes and lizards.
It is true that the females of some spider species eat the males after mating. Males sometimes get around this by offering the female a fly or other prey that she will eat while he mates with her.
How do spiders hunt prey?
Many spiders do not really hunt, but weave webs to catch their prey. Prey, usually an insect, stumbles upon a web, the spider bites it and wraps it in silk. He can start eating the loot right here or cache it for later.
Fishing spiders spend almost their entire life in the water and build nets in the shape of diving bells. These bells are filled with air, and the spider lives inside them, like its earthly counterparts in their nets. When the prey touches the bell or its securing threads, the spider grabs it.
Other spiders weave tiny webs that they use as webs. They hold cobwebs in their first pair of legs and catch their prey with them. Some species release the web when prey enters it, while others hold onto it to catch their prey. There are also spiders that make bolas. These are adult females related to Mastophora genus. They create a strip of silk with a drop of sticky silk at one end to catch moths. Not only that, but the silk also smells like moth pheromones. Males and Mastophora spiders simply mimic pheromones and grab the moth with their front paws.
Other spiders use a loophole plan. They live in burrows and construct hatches attached to silk threads. When the prey passes along these threads, the spider is alert, shoots and grabs the prey.
Wolf spiders and jumping spiders actually hunt down their prey. Because of this, these creatures have excellent eyesight and, in particular, wolf spiders are colored according to their environment. On a sandy background, it can be very difficult to see a brownish-brown wolf spider. Some seem smart enough to lure prey out of their hiding place. Nature has even created spiders that mimic their prey. Ants that mimic jumping spiders look and behave very much like ants in order to better penetrate their nests and grab either the ants or the aphids they raise. Interestingly, scientists believe that the mimicry of ants arose in such a way that the spider could not be hunted by predators that eat spiders.
When a jumping spider finds potential prey, it can chase the prey for a while, then orient itself, lay the cable and jump.
Crab spiders wait for flowers to lure their prey into an ambush. They can even change their color to match the color of the flower. The venom of the crab spider is very potent, so it can successfully catch animals that are much larger than itself.
What kind of animals do spiders eat?
For creatures that can move or are insensitive to its venom, the spider is an essential part of the diet. Even humans eat spiders. The goliath tarantula is eaten after irritating hair has been singed, wrapped in banana leaves and fried. It should taste like shrimp. Other spiders on the human menu are the Thai black spider and the golden spider that is said to taste like foie gras. Other animals that eat spiders:
