Entomology is The Science That Studies

Insects are arthropods (a phylum of animals) Entomology is The Science That Studies that have six legs and two antennae. There are over 400,000 species of insects, excluding spiders and mites. Many insect species play a role in pollination. In fact, some bees and butterflies are responsible for pollinating approximately 90% of flowering plants on Earth. Insects eat pollen, nectar, and other types of food. Insects are not only beneficial to humans and other animals, but they are useful in agriculture and medicine.


Entomology is The Science That Studies Parasitoids are insects that live inside their host and use them as hosts to lay their eggs. These insects then go on to kill any offspring of the host after hatching. Parasitoid insects are also called predators because they prey on other insects. An example of a parasitoid is the ladybird beetle, which lays its eggs on aphids, causing the aphid to burst open and release the larva, killing the aphid.


Predators are animals that eat other animals. A predator does not need to capture its prey; it simply eats it. Animals that attack others are known as hunters. Hunters do not always need to hunt for food either. Herbivores, like cows, graze grasses and other vegetation. Herbalists believe that certain herbs help protect livestock from parasites and disease.

Pest A pest is any organism that causes damage to crops or other valuable property. Common examples of pests include weeds, rodents, and fungi. Some people consider ants and termites pests. However, these creatures actually clean up dead bodies and decompose debris. Ants were once considered pests, but now we know they are beneficial.


Symbiosis means living together. In biology symbiosis refers to a relationship between two organisms where one helps the other. Sometimes, one organism benefits at the expense of the other. For instance, bacteria living in our intestines benefit us by breaking down food that would otherwise harm us.

Endoparasitism means living inside another creature. An endoparasite lives inside another living organism. One example of an endoparasite is tapeworms. Tapeworms live in the intestine of mammals, including humans. Another example of an endoparamisitic is the roundworm. Roundworms live in the gut of birds and reptiles.


Mutualism is a type of symbiosis where both parties gain something from the interaction. For example, mycorrhizae is a mutualistic fungus that grows around roots of plants. Other examples of mutualisms include lichens, which are a combination of algae and fungi, and coral reefs, which are colonies of corals and sea anemones.

  • Insects
    Insects are arthropods (joint-legged invertebrates) that have segmented bodies and jointed appendages. They have a hard outer covering called a cuticle, and internal organs including digestive systems, nervous system, respiratory system, circulatory system, reproductive system, and muscles. An insect’s body consists of three basic parts: head, thorax, and abdomen.
  • Arachnids
    Arachnids are a type of insect closely related to spiders and scorpions. Most arachnids have eight legs although some species have only four. Their mouthparts consist of two pairs of jaws armed with teeth and two pairs of antennae.
  • Butterflies
    Butterflies are insects belonging to the order Lepidoptera. Butterflies are characterized by their wings having a flap shaped like a butterfly. Their larvae are caterpillars.
  • Beetles
    Beetles are members of the order Coleoptera. A beetle is a member of the suborder Polyphaga, which includes scarabs, cockroaches, mantises, grasshoppers, leaf beetles, weevils, and others. They are characterized by six pair of legs, two prothoracic glands, and mandibles (chewing apparatus). Many species are omnivorous, eating both plant material and animal matter.
  • Bees
    Bees are insects of the superfamily Apoidea. There are about 20,000 known bee species. Honey bees are social animals and possess a highly developed intelligence. The honeybee is native to Eurasia and Africa.
  • Caterpillars
    Caterpillars are larval stage of butterflies, moths, skippers, bugs, and lepidopterans. These creatures are generally soft bodied, legless, and green or brownish in color. While they do not possess wings, they do have a tough chitinous exoskeleton.
  • Cockroaches
    The cockroach family Blattidae contains several hundred species. Members of the genus Periplaneta have been used extensively as models for research on insect physiology and behavior.
