Bugs and Butterflies...Where Do They Go For The Winter





There is a cute saying we quote to children, "snug as a bug in a rug". That is very true when it comes to the survival of our backyard bugs and butterflies during the harsh, cold winter months.
Most of us are aware of the long migration south of the Monarch butterlies, but butterflies and other insects do not migrate. They cleverly hidden in the landscape.

Butterflies and other insects slow down their metabolisms in a process called diapause. They rid most of the water from their bodies to avoid freezing and there are certain chemicals in their bodies that act as antifreeze.

Different types of butterflies are in various stages of their life cycles during the winter months. Some will overwinter as an egg or ovum, some as a larva or caterpillar, some as a pupa or chrysalis and some as adults.

In order to accomplish any of this, butterflies need the proper conditions. There is a reason nature seems to be so untidy by late autumn when everything dies back for the winter. Without places of shelter in leaf litter, tree bark, plant stalks, seed heads and brush piles, these insects wouldn't survive.
This is why it is so important to hold off on your garden clean up until spring. Raking, bagging and disposing of all those fall leaves is actually destroying countless insects. If you want your yard and garden to come alive again in the spring, you simply cannot interfere with too much cleaning up and cutting back.

Below are a few examples of where our flying flower beauties go for the winter:

The Viceroys, who look so much like the Monarchs,are in the caterpillar stage. The chew a leaf into a certain shape, roll up inside it to form a tent form and then fasten to a plant stalk.

Fritillaries, Crescents and Skippers hatch from their eggs in the fall and sleep through the winter as caterpillars.
