Help butterflies get through winter

Butterflies color our gardens spring through fall, but where to they go in winter? They have to be somewhere! While the Monarch butterfly is famous for it’s epic migrations, many others survive the winter right here at home. But they do need our help every bit as much as the monarch!

Feel good about leaving things messy.

In addition to growing a variety of species and generous quantity of Asclepias plants to feed monarchs, gardeners should also consider other elements to gardening that can mean life or death to other butterfly species, including leaving plant debris in place over the winter months to provide shelter. Here are some notes collected from Wildlife Gardeners list serve comments. The page also includes great lists of larval host plants for a variety of butterfly species:

• Fourth-stage caterpillars hibernate in rolled leaves on the ground.

• Fourth-stage caterpillars hibernate in rolled leaves on the ground.

• Third-stage caterpillars make a shelter from a rolled leaf tip in which to spend the winter.

• Partially-grown caterpillars hibernate at the base of the host plant.

• Some caterpillars overwinter in seed pods of food plant.

• Some caterpillars overwinter in silken nests below host plants on ground.

• Some adults overwinter in the shelter of hollow trees, under bark or utilize seasonal outbuildings.

• Some adult hibernators find protection in hollow logs, wood piles and loose bark.
