Why Does Spiders Eat Flies?
Spiders are insects that are a part of the food chain. They feed on other insects, especially flies. They are also good at eating bugs, like mosquitoes and moths.
Spiders belong to the phylum Arthropoda and are part of the family Arachnida. They have jointed appendages attached in pairs. These appendages include their fangs, which inject venom. In addition to this, they have jaws, which hinge at the rear corners of the insect’s mouth. They also have a cephalothorax, which is a triangular section on the top of the insect’s head.
A number of spiders eat plants. This practice has been reported in more than 60 species of spiders, including those found in every continent except Antarctica. Some spiders actually pierce leaves with their chelicerae. Others eat pollen, nectar, and honeydew.
Spiders’ digestive juices contain powerful enzymes, which are used to digest solid parts of their prey. In addition, they re-use digestive enzymes. Some of these enzymes are stored in the foregut of the spider.
Most spiders do not eat animals, though some do. The largest orbweaving spiders, for instance, will suckulate their prey. The prey is wrapped in silk. The spider then vomits its digested fluid over the prey. This process repeats over and over until the prey is dead. Then the spider discards the small ball of residue.
Another common plant-eating practice of spiders is to eat the exoskeleton of the insect. This gives the spider a break from hunting.
