Butterflies & moths
Some hide as caterpillars under leaves; others blend cocoons or chrysalises into the leaf layer. The exact winter strategy depends on the species.
Leaf litter is winter shelter and a year-round food source for an astonishing variety of garden visitors.
Illustrated icons are playful stand-ins for real wildlife. Whether a species lives in your particular yard depends on habitat and location.
Some hide as caterpillars under leaves; others blend cocoons or chrysalises into the leaf layer. The exact winter strategy depends on the species.
After mating, new queens seek protected overwintering spots in soil, often beneath surface cover. Most workers do not survive winter.
Many species spend an extended larval stage in damp soil and leaf litter, feeding on small invertebrates. They need moisture and protection.
Some woolly bear caterpillars shelter among leaf litter and vegetation through winter, using a remarkable cold-tolerance strategy.
Many helpful insect predators use leaves, bark or stems to find winter refuge. Not every beetle has the same needs.
Juncos, sparrows and other ground-foragers investigate fallen leaves for seeds and tiny animals; insect-eating birds benefit from this food web.
Snails, worms, millipedes and other soil animals help break down litter or use it as food and cover, forming a key part of the garden ecosystem.
Depending on the local habitat, leaf layers provide humidity, concealment and foraging areas for small animals such as toads.
Leaves help, but they are one piece of the habitat puzzle. Choose locally appropriate native plants, provide flowers across the growing season, limit pesticides, and keep some natural shelter such as hollow stems and logs. Protecting habitat from fall through spring gives visiting insects a better chance.
