Insects are easily the most abundant and diverse group of animals, with over 24,000 species in the UK alone. They can be found in almost every habitat on Earth and are fundamentally important to ecology, conservation, food production, animal and human health, and biodiversity. They are a prominent feature of almost every food web in the UK and worldwide. They can be directly beneficial to humans, servicing the ecosystems through pollination, nutrient cycling and predation of plant pests, or they can be detrimental, as vectors of disease and crop pests. This is why the Royal Entomological Society, through its National Insect Week (NIW), aims to raise awareness and understanding of insects and other invertebrates and of the vital role they play in humans' lives. During NIW over 70 partner organisations come together to celebrate insects and entomology (the study of insects). NIW particularly aims to allow young people to learn more about insects, through providing resources and supporting events nationwide. This article provides a number of ways in which teachers can get involved in the campaign.
