Many people wonder whether tortoiseshell butterflies hibernation during winter. It’s true that these insects have a winter life cycle, but what does this mean for their owners? First of all, it means that they can’t survive winter in a house! The best thing you can do is to re-house your butterfly when it’s in your house. This will prevent the butterfly from being disturbed, but it’s also important to release it outside during the warmer months.

When does tortoiseshell butterflies hibernation occur? It’s believed that they’ll hibernate during mid-July, right before the Butterfly Conservation’s Big Butterfly Count.

The Tortoiseshell butterfly’s life cycle is short, lasting only about four weeks from egg to adult. Most species of tortoiseshells hibernate indoors. They’ll stay inside the house until springtime, when the weather is warmer. The adults will be back in mid-July, and they’ll emerge in the spring. If you can’t find them anywhere, you’ll have to wait until the butterfly is on the wing and see if you can find it.

The Compton Tortoiseshell butterfly overwinters inside houses. They come inside during the late summer and early autumn to get shelter from cold weather. They need cool, sheltered conditions to survive the winter. Heat from Christmas heating can result in premature awaking of the butterfly. During this period, nectar is scarce and the temperatures inside the house are too high for them to survive.
