Difference between spider and insect

The main difference between spider and insect is that the body of the spider is divided into two regions: cephalothorax and abdomen, while the body of the insect is divided into three regions: head, thorax and abdomen …

Spider versus insect

The spider consists of two body legs: cephalothorax and abdomen, eight predatory arachnids, while the insect has six legs and has one or two pairs of wings. The spider belongs to the phylum Arthropoda and the class Arachnida, while the insect belongs to the phylum Arthropoda and the class Insecta. The spider lives in the terrestrial environment; on the other hand, the insect can be aquatic and parasitic, but some live mainly in a terrestrial environment. Spider has four pairs of appendages; on the other hand, the insect has three pairs of appendages. There are no spider wings, but many insects have wings. The spider used to sense through its cuticles, while insects detect through its antenna. Spider has chelicerae; on the contrary, the insect has a proboscis, mandibles and maxilla. Spider has one to six pairs of simple eyes, while the insect has a pair of compound eyes. The spider breathes through the windpipe and the lungs of the books at the same time, while the insects only breathe through the windpipe. The color of the spider’s blood is blue; on the other hand, the insect has colorless blood. The spider is primarily a predator, while insects feed on both animal and plant materials. The spider undergoes an incomplete metamorphosis, while the insect undergoes a complete metamorphosis. The spider is primarily a predator, while insects feed on both animal and plant materials. The spider undergoes an incomplete metamorphosis, while the insect undergoes a complete metamorphosis. The spider is primarily a predator, while insects feed on both animal and plant materials. The spider undergoes an incomplete metamorphosis, while the insect undergoes a complete metamorphosis.

Comparative chart

Spider consists of two body segments: cephalothorax and abdomen, with eight legs and are predatory arachnids. Around 50,000 species of spiders can be found around the world (except Antarctica). The body of the spider is divided into two regions: cephalothorax and abdomen. Spider has one to six pairs of simple eyes. The spider has four pairs of appendages or legs that connect to the cephalothorax. The spider’s cephalothorax consists of the brain, stomach, mouth fangs, and glands, which produce venom. The spider’s abdomen is made up of a row-like gland from which the silk is released to the outside. To stick their body to the web, they secrete oils. The hairs that are present on the spider’s legs are sensitive to odor and vibrations. Each leg has six joints. So they have 48 knees. The spider used to feed on liquid food. That is why they have a tiny intestine. Most spiders are predators that inject venom to kill their prey, although there are herbivorous spiders as well. The spider undergoes an incomplete metamorphosis. There are three stages of its life cycle as egg, larva and adult.

What is an insect?

The insect has six legs and one or two pairs of wings and are small arthropods. Around 6 to 10 million insects are found worldwide. Most of them live in terrestrial environments. The body is divided into the head, thorax, and abdomen. They have a pair of compound eyes and a pair of antennae. Characteristically, two pairs of wings connected to the thorax. Insects have six legs. The body of the insect covered by an exoskeleton, which is made up of chitin. Insects feed on animal material and also on plants. Feeding is done through three types; chew, fluff and suck. Chewing insects have jaws, lips, and jaws as mouthparts. Respiration in insects occurs through the windpipe. The insects undergo a complete metamorphosis. The life cycle stages are egg, larva, pupa, and adult. Insects normally move by walking, flying, and sometimes swimming. Water spiders are capable of walking on the surface of the water.

Key differences

1. Spider consisting of two body segments: cephalothorax and abdomen, predatory and eight-legged arachnids, while the insect has six legs and has one or two pairs of wings and are small arthropods.
2. The spider belongs to the phylum Arthropoda and the class Arachnida, while the insect belongs to the phylum Arthropoda and the class Insecta.
3. The spider lives in the terrestrial environment; on the other hand, the insect can be aquatic and parasitic, but some live mainly in a terrestrial environment.
4. The body of the spider is divided into cephalothorax and abdomen; on the contrary, the body of an insect is divided into the head, thorax and abdomen.
5. Spider has four pairs of appendages; on the other hand, the insect has three pairs of appendages.
6. There are no spider wings, but many insects have wings.
7. The spider used to sense through its cuticles, while insects detect through its antenna.
8. Spider has chelicerae; on the contrary, the insect has a proboscis, mandibles and maxilla.
9. The spider has one to six pairs of simple eyes, while the insect has one pair of compound eyes.
10. The spider breathes through the windpipe and the lungs of the books at the same time, while the insects only breathe through the windpipe.
11. The color of the spider’s blood is blue; on the other hand, the insect has colorless blood.
12. The spider is primarily a predator, while insects feed on both animal and plant materials.
13. The spider undergoes an incomplete metamorphosis, while the insect undergoes a complete metamorphosis.

The above discussion concludes that the spider consists of two body segments: cephalothorax and abdomen, eight-legged predatory arachnids, while the insect has six legs and one or two pairs of wings and are small arthropods.
