They catch food using their webs, which are very large and very strong.
Spiders spin webs to catch prey. The silk they produce is strong and sticky, helping them immobilize insects that get caught. The web also serves as a shelter and a place for spiders to lay their eggs.
Spiders spin webs to catch prey, protect themselves, and lay eggs. The silk they produce is strong and sticky, helping them trap insects for food and create a safe shelter.
There are several ways that spider use to catch their food. They spin webs to catch insects or they just go look for food. Some of them lay in wait and then ambush an insect as it goes by. Others dig burrows and wait for passing prey before they pull them in.
A web
to trap food such as flies or bees
Spiders make webs to catch prey (food). When a small flying insect flies into the web it's caught. The spider than comes over and using its fangs injects poison to kill or paralyze the insect, then eats it.
Usually they'll catch their food with the spiderwebs they make. First spiders weave their web. Then they wait for an insect to fly into the web. They wrap the insect in their spider silk which is what the web is made from. Then the spider injects the insect with venom that either paralyze or kills the insect. The venom makes the insect into liquid. Then the spider eats it.
Cobwebs begin with a strand of spider's silk, but it attracts ionized dust motes, and builds into a chain. Cobwebs are made from spiders, but are different than spiderwebs in that they are not for the purpose of catching prey.
Cobwebs are formed by spiders to catch prey. Spiders spin silk threads to create webs in corners and other secluded areas where they can wait for insects to get caught in the sticky strands. The presence of cobwebs in homes and buildings is a natural result of spiders seeking shelter and food sources indoors.
so they can catch their food. also to carry their babies in.
Spiders hang from webs because they are skilled predators that use their silk to catch prey. This allows them to catch food efficiently and safely, rather than crawling on the ground like other insects.
Spiders that don't use webs to catch their prey are known as hunting spiders. They actively stalk and hunt down their prey instead of relying on webs to trap them. Examples of hunting spiders include wolf spiders, jumping spiders, and crab spiders.
