How insects survive/appear after winter, in especially cold climates

Question

The explanation for insects with short life spans, too be abundant in northern regions, especially northern Canada.

No insects all winter, temperatures reaching below -40. But come summer time there’s flies, bees, hornets, grasshoppers.

I’m not sure if the insects somehow survive the winter, or if it’s just their pupae/egg stages?

Answer 1

A lot of insects have cycles that coincide with the year, so basically they lay eggs then die to the cold, and the eggs survive the freezing and then hatch in the spring.

And a lot of insects are able to survive the winter because they build nests that are insulated from the cold. Bees for example, ants, etc.
