Why we need insects and spiders,  which of them are declining, and which moving in.

Insects and spiders matter to us because of their enormous contributions to ecosystems, including in food webs, for pollination, enjoyment, and pest control. Some set back agriculture and forestry, and can harm health of humans, livestock, and wildlife. Some species seem to be in decline, or are being replaced. We will see examples of the lives of insects and spiders in our area, including some that are worthy of conservation. Citizen science participation and personal interest expressed by the public and students is an important part.
