Leave those Leaves!
The larvae of many butterflies and moths spend the winter under a protective blanket of fallen leaves. That woolly bear caterpillar you saw crossing the road is headed for winter quarters under leaves, logs, or tree bark! Great spangled fritillary caterpillars crawl into the leaf litter at the base of their host plant (violets) to wait out the winter. And the eggs of the red-banded hairstreak hatch on fallen oak leaves. When the caterpillars hatch, they’ll use those leaves as their primary food source as well as shelter.
