Insects sustain our ecosystems, as a food source and pollinators of 90% of all plants, but their numbers have dropped by half in the last 50 years. However, growing certain plants directly benefits birds and helps insects keep the natural world ticking. BirdNote®'s Mary McCann has the story.

BASCOMB: This time of year many of us may be cursing the bugs that bite.
But as BirdNote’s Mary McCann reports, our tormentors are a delight
for birds.

Insects Are Essential

MCCANN:A tiny Nashville Warbler flies to its nest, a fat caterpillar clamped in its beak. Nearly all of North America’s smaller birds, from this warbler to chickadees to thrushes, raise their young on insects—especially insect larvae like this juicy caterpillar.

MCCANN:Insects sustain 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 E.O. Wilson put it, insects are “the little things that run the world.”

Though insects are small, easily overlooked, and often vilified, most are beneficial. But their numbers have dropped by half in the last 50 years, so it’s now critical to help foster insects. One concrete 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 Midwest, buttonbush 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 ticking.
