SO MANY INSECTS
•6,000,000 to 10,000,000 different
kinds of insects in the world
•Insects outnumber all other kinds of
animals put together!
•Found in almost every place on Earth
KINDS OF INSECTS
• TERRESTRIAL= live on land
• AQUATIC= live in water for part or all of
their lives
• Move by walking, flying or swimming

bodies can change shape as they
grow up
Let’s build an insect!
First we need a frame to build on:
EXOSKELETON
EXO= outside
SKELETON= supporting structure
INSECT= divided body, “cut into”
• SEGMENTED bodies
HEAD
• Encased in one piece of hard exoskeleton
• Contains SENSING parts:
– Antennae
– Eyes/light sensors
• Compound eyes
• Mouthparts
THORAX= middle section
armor protecting CHEST and BACK
• LEGS: 3 pairs, 6 legs total
• WINGS
ABDOMEN= last section
• Has stomach inside
• Usually not as protected
• Sometimes it has special parts,
depending on the type of insect
– stingers

• Pollination: plants and insects
help each other
WHY ARE INSECTS IMPORTANT?
• Honey, wax, silk
• Scientific discovery
• Food and culture
• Medicine
• Ecosystems
WHY ARE INSECTS IMPORTANT?
• Pests
–Parasites
–Eat crops
• Some insects eat other bad
insects good for us!
– ladybugs
