Animals that come inside for the winter

In temperate regions there is very little evidence of insect life outdoors during the winter. This is simply because the low temperatures render insects incapable of activity, and even if they could move around there would be nothing for them to feed on.

When autumn comes insects have to find sheltered places where they can spend the winter and for this outhouses and lofts are very suitable. They must also have reached a stage in their life history in which they can go without food and can withstand the unfavourable climatic conditions. The stage concerned will vary from species to species. Some overwinter as eggs, some as larvae and quite a few as pupae, e.g. cabbage white butterflies. There are others which spend the winter as adult insects, as for example lacewings, cluster flies and small tortoiseshell butterflies.
