Insects in ecosystems

Insects in ecosystems: the many roles insects play. Pollinators (bees, butterflies, hoverflies), decomposers (dung beetles, fly larvae), food source for birds, bats, fish, and frogs, and pest controllers (ladybirds eating aphids). The thought experiment: what would happen if all insects disappeared?

How to tell they’ve got it

Tick these off as you see them — no test required.

Name at least three different ecological roles that insects play such as pollinator, decomposer, and food source
Explain how the removal of one insect group like bees would affect plants, other animals, and humans
Describe a specific example of insects as pest controllers such as ladybirds controlling aphid populations

Try this together

If you asked your child what would happen if all the insects in the world disappeared tomorrow, could they explain the chain of problems that would cause — for plants, animals, and people?
