do all insects die in winter and the eggs hatch in spring?

Question

I'm wondering how they survive year to year

So there is a total die off, and the hemisphere is insect free till eggs hatch in spring (laid the autumn before)?

Answer 1

John R is right. I just wanted to add that monarch butterflies are another one that survives the winter, but by migrating the length of North America to a wintering ground near Mexico City.

Answer 2

Generally insects die off in the winter, except for the occasional lucky one. The eggs hatch in spring, but are laid by the insects that survived. Certain insects lay eggs in summer or autumn, and the insect larvae survive the winter by building cocoons and reemerge in the spring.

Answer 3

Not at all. A number of insects overwinter in sheltered places until it warms up. Social insects like bees and wasps can have everybody but the queens die off, and the queens hang out in a state similar to hibernation until spring, when they come out, build a new nest and start pumping out the kids. There are a variety of ways that insects deal with seasonality.

Answer 4

Think of it this way: any combination of survival/overwintering strategy you can think of, insects do it.
