Insect body parts

What this diagram shows

Every adult insect has a body in three parts: head, thorax and abdomen. It has six jointed legs, all attached to the thorax, and one pair of antennae. Most insects also have wings, and many have large compound eyes. This diagram uses a honeybee, drawn from above with its wings spread, so all six legs are visible. Explore, Labels and Quiz me work as on our other diagrams.

The Insect or not? game below the picture shows animals one at a time. The student decides whether each one is an insect and gets a reason after every answer. It includes some tricky ones: spiders, scorpions and crabs have jointed legs but are not insects, while a caterpillar is.

Why sorting helps

Young children often call any small crawling thing a bug or an insect. Knowing the rule (three body parts, six legs) is one step; using it to sort real animals is what makes it stick. Asking "How many legs?" and "How many body parts?" each time also builds the habit of looking for evidence before deciding.

Common misconceptions

• Spiders are not insects. They have eight legs and two body parts, and they belong to a group called arachnids.
• Insect legs grow from the thorax, not the abdomen. Children often draw them all along the body.
• Not every insect has wings. Worker ants, for example, have none, but they still have three body parts and six legs.
• A caterpillar is an insect. It is the young stage, or larva, of a butterfly or moth.

A 10-minute insect activity

• Ask the student to draw an insect from memory and count its legs.
• In Explore, tap each part of the bee and compare it with the drawing.
• Play Insect or not? together, asking for a reason before each answer.
• Go outside, or look at photos, and find two real insects. Check the rule on each one.
• Finish with a Quiz me round.

Where this fits in school

• US, kindergarten to grade 2: children observe and compare animals and their body parts as they learn how living things are alike and different.
• US, grade 4: NGSS 4-LS1-1 asks students to argue that animals have external structures, such as legs, wings and antennae, that support survival.
• England, Years 1 and 2: pupils identify, name and compare a variety of common animals, and many schools study minibeasts.
• England, Year 4: pupils group living things and use classification keys, where insect features are a common example.
