Entomology - Definition, Examples, Quiz, FAQ, Trivia
Discover the amazing world of insects and why they're important to our planet!
What is Entomology?
Entomology is the scientific study of insects! Scientists who study insects are called entomologists.
Insects are the most diverse group of animals on Earth - there are over a million known species! They live almost everywhere: in forests, deserts, rivers, and even in our homes. Entomologists learn about how insects live, grow, and interact with the world around them.
Entomology is part of a larger science called zoology, which is the study of all animals. But insects are so special and numerous that they have their own branch of science!
Did You Know?
For every human on Earth, there are about 200 million insects! They make up about 80% of all animal species.
Why Insects Matter
Insects might be small, but they have a huge impact on our world! Here's why they're so important:
Pollination
Bees, butterflies, and other insects help plants make fruits and seeds by moving pollen between flowers
Decomposition
Insects like beetles and ants break down dead plants and animals, recycling nutrients
Food Source
Insects are food for birds, fish, frogs, and many other animals
Scientific Research
Insects help scientists learn about genetics, behavior, and ecosystems
Entomology also helps us with pest control. Some insects damage crops or spread diseases. Entomologists study these insects to find safe ways to manage them. This area is called economic entomology.
Another special field is forensic entomology, where scientists study insects to help solve crimes. Insects on a body can tell investigators important information!
Insect Anatomy
All insects share some special body features. This is called their morphology - the study of an organism's form and structure.
Here are the main parts of an insect:
Head
Contains the brain, eyes, antennae, and mouthparts
Thorax
Middle section where legs and wings attach
Abdomen
Contains digestive and reproductive organs
Exoskeleton
Hard outer shell that protects the insect
Six Legs
All insects have exactly six legs
Entomologists also study insect physiology - how insect bodies work. This includes how they breathe through tiny holes called spiracles, how their circulatory system works, and how they digest food.
Insect behavior is another fascinating area. Entomologists observe how insects communicate, find food, build nests, and care for their young.
Amazing Adaptation!
Some insects like walking sticks have evolved to look exactly like twigs to hide from predators!
Insect Classification
With so many insect species, scientists need a way to organize them. This is called insect taxonomy - the science of naming and classifying insects.
Insects are classified into groups called orders based on their physical characteristics. Here are some major insect orders:
Coleoptera
Beetles - the largest group with hard wing covers
Lepidoptera
Butterflies and moths - with scaly wings
Hymenoptera
Ants, bees, wasps - often social insects
Diptera
Flies - with only one pair of wings
Entomologists also study insect ecology - how insects interact with their environment and other living things. This helps us understand biodiversity and how to protect ecosystems.
When scientists discover a new insect, they carefully examine it to determine what group it belongs to. This helps us understand how insects are related and how they evolved.

Frequently Asked Questions
Here are answers to some common questions about insects:
Amazing Insect Facts
Discover some incredible facts about insects!
Super Strength
Ants can carry objects up to 50 times their own body weight! If humans had that strength, a 150-pound person could lift a car!
Taste with Feet
Butterflies taste with their feet! They have taste sensors on their feet that help them find the right plants to lay their eggs on.
Navigation Experts
Honeybees perform a "waggle dance" to tell other bees where to find flowers. The dance communicates direction and distance!
Diversity Champions
Beetles make up about 25% of all known animal species! There are more than 400,000 species of beetles on Earth.
