Leave a little mess this year. Why it matters: Butterflies many species overwinter as chrysalises on fallen leaves 曆 Fireflies their larvae live under leaf litter, waiting for spring glow Native bees thousands nest in soil beneath autumn leaves Ladybugs clusters hibernate in piles of leaves Moths & other pollinators leaf litter shelters their eggs & pupae A tidy yard to us can mean an empty graveyard to them. Let the leaves rest and the wildlife will thank you next spring.
