Insects sustain our ecosystems, providing food and pollinating 90% of all plants, but their numbers have halved in the past 50 years. However, growing certain plants directly benefits birds and helps insects run the natural world. BirdNote®’s Mary McCann has the story.

BASCOMB: This time of year, maybe a lot of us curse biting insects.
But as BirdNote’s Mary McCann reports, our executioners are a delight.

Insects are essential

MCCANN: A tiny Nashville Warbler flies toward its nest, a large caterpillar clutched in its beak. Almost every small bird in North America, from this warbler to chickadees to thrushes, raise their young on insects, especially insect larvae like this juicy caterpillar.

MCCANN: Insects support our ecosystems, and not just as a food source. They also pollinate 90% of all plants. And without plants at the heart of the food web, life on earth would simply collapse. As naturalist EO Wilson said, insects are “the little things that run the world”.

Although insects are small, easily overlooked and often reviled, most are beneficial. But their numbers have halved in the past 50 years, so helping to foster insects is now essential. One practical way to help is to grow native plants that provide food and shelter for insects like caterpillars.

For example, in the eastern United States and the Midwest, the button supports 18 different species of caterpillars and also provides food for birds in the form of nectar and seeds.

Growing such plants directly benefits birds and helps insects keep the natural world going.
