The Importance of Insects Some insects are harmful: Some insects are beneficial: Pollinate flowers Important Products Research Balance Nature Destroy food crops Stings & Bites Causes Sickness Money Loss
Metamorphosis: A change in physical form The insect’s exoskeleton does not grow with them and must be shed and re-grown each time they get larger. Monarch Caterpillar Monarch Butterfly COMPLETE CHANGEsmall change Worker Termite Termite Nymph
An insect has four characteristics: 1. Three body segments: Head, Thorax and Abdomen Dragonfly HEAD: The eyes, antennae, and mouthparts are on the head. THORAX: The 3 pairs of legs and wings are attached to this body segment. ABDOMEN: This body segment holds all reproductive organs. 3. Three pairs of legs (6 legs in total) 2. One pair of antennae 4. Usually 1 or 2 pairs of wings

Below there are some pictures of some insects. Can you pick out the characteristics they all have in common?
Appearing below will be pictures of different arthropods. Some are insects and some are not. Armed with your new definition, can you pick out the non-insects?
