Insect Adaptations

Science · Insects & Minibeasts · conceptual

Adaptation and evolution in insects: peppered moths as a famous example of natural selection (dark moths survived better on soot-covered trees during the Industrial Revolution). Stick insects evolved to look like twigs. Ant-mimicking spiders evolved to fool predators. How small changes over many generations lead to remarkable disguises.

What mastery looks like

  • Retell the peppered moth story and explain how the environment changed which colour moth survived best
  • Describe how a stick insect's body shape is an adaptation that helps it avoid being eaten
  • Explain that adaptations develop over many generations through natural selection, not during one insect's lifetime

Check your understanding

Can Insect Adaptations explain why peppered moths changed colour during the Industrial Revolution — and how that's an example of how living things adapt over many generations?
