Insects and Spiders are from the Arthropoda phylum with joint legs and exoskeletons. Insects and spiders are very prominent species of animals in the world.
The insects and spiders are different from a different class of Arthropoda. They have distinct characteristics, and insects are the food of spiders.
Key Takeaways
- Spiders belong to the class Arachnida, whereas insects are part of Insecta, indicating distinct evolutionary backgrounds and physical characteristics.
- Insects possess six legs and three body segments (head, thorax, and abdomen), while spiders have eight legs and a two-segmented body (cephalothorax and abdomen).
- Spiders exclusively rely on venomous fangs to subdue prey, whereas insects employ various methods of predation or feeding, such as chewing, sucking, or piercing.
Spiders vs Insects
The class to which spiders belong is Archinda. Spiders have eight eyes and legs. The population of insects is controlled by spiders. Spiders hunt insects. Spiders do not live in cold places. The class to which insects belong is Insecta. Insects have six legs. Some insects can be beneficial, but some can be harmful. Some insects produce honey.
Spiders are predators that hunt other arthropods, insects. On average, a spider consumes 0.089g of insects per day.
Spiders are of the order Araneae and are not found in oceans and cold places like Antarctica Spiders are very important to balance the ecosystem of nature, as they control the insect populations. They are also used in the agricultural field to reduce the pest.
Insects are from class Insecta and order. These are the largest group of Arthropoda in which some insects are beneficial to the natural ecosystem, and some harm humans and nature.
They become food for other animals like spiders, birds, reptiles, and fishes. Some insects pollinate flowers, some produce honey, wax, and silk, and some help maintain the nutrient cycle.
Comparison Table
| Parameters of Comparison | Spiders | Insects |
|---|---|---|
| Class | Archinda | Insecta |
| Body parts | It has two main body parts that are the cephalothorax and abdomen. | It has three main body parts that are the head, thorax, and abdomen |
| Characteristics | It has eight legs and eight eyes | It has six legs and two eyes |
| Benefits | Spiders eat insects, and their venom is used in medicines. Silk is used in war and reduces the spread of diseases. | Some insects are used to produce honey, silk, gut, beeswax, pollination, dyes, and others. |
| Harmful | Spiders do not harm humans. | Insects spread diseases like skin irritations, infection, malaria, yellow fever, dengue, and others. |
What are Spiders?
Arthropoda phylum is a group which has three-fourths of the species. It has a segmented body, jointed legs, and an exoskeleton. The Arthropoda have different classes that group similar species.
Arachnida is a class of Arthropoda that consists of animals with two-segmented body parts, eight legs, and eight eyes. Some species have four eyes, and some do not have eyes in this group.
Spiders are from the Arachnida class and order Araneae. There are modern spiders, primitive spiders, and mesothelae.
Spiders are beneficial to humans and the natural ecosystem as they prey on insects and other small creatures. The spider’s silk gland is used to construct cocoons, webs, retreats, draglines, and others.
The venom gland is used to prey on insects. Spiders create different webs to attach to insects, such as silken, funnel, sheet, and orb webs. Some spiders do not build webs, and they hunt insects like Salticidae. They are known as sit-and-wait predators.
Spiders do not harm humans, though they bite people but do not lead to death or give birth to new diseases. The pain can be dealt with first aid. Spiders benefit humans by preying on insects that spread diseases.
They keep homes and gardens free from insects. Its venom is used in creating medicines. They are also a sign of good luck in some cultures.
What are Insects?
Insects are also one of the groups of Arthropoda phylum from class Insecta. Insects have a head, thorax, abdomen, a pair of wings, a pair of antennae, three pairs of legs, and compound eyes.
A vast group of insects are present, out of which are beneficial to humankind, some harm humans, and some are neutral, contributing to the well-being of humans and the ecosystem. Insects occupy every place on the earth. They are small in size and have reproductive potential.
Some of the products produced by insects are honey, gut, beeswax, dyes, propolis, and bee milk. Insects also carry out pollination activity in the plant’s reproduction. Especially bees carry out pollination as they get energy from the flowers.
Some insects are also helpful in the agricultural field. Some insects are imported from one country to another to control the weeds population.
People consume Pedigo and Rice as they provide proteins and minerals. Insects like fly larvae are used to treat wounds. Dead insects create organic matter and promote natural fertilizer.
Some insects harm humans by spreading diseases like malaria, yellow fever, and dengue, destroying the tissue. They cause irritation and skin allergy in sensitive people.
Main Differences Between Spiders and Insects
- Spiders and insects are a family of Arthropoda but from different classes. The spiders class is Archinda, and the subclass is Araneae, and the class of insects in Insecta.
- Spiders have eight legs and eight eyes, but insects have only six legs and two compound eyes.
- Spiders do not have wings and antennae-like insects.
- The cephalothorax and abdomen are the two main body parts of Spiders. On the other hand, the head, thorax, and abdomen are insects’ three main body parts.
- Insects harm humans by spreading diseases. Spiders do not harm humans instead it reduces spread of diseases by preying on insects.
