Now, this sounds like a great way to spend a north European winter...anyone tempted?
But more fundamentally, insects undergo body changes that favor their cold-hardiness. One of the most common changes is that they produce glycerol in their blood -- a natural anti-freeze. Insects also can partially dehydrate their cells which further lowers their freezing point.
Furthermore, to ensure that the insect does not emerge prematurely during a winter warm spell, it goes into a state of semi-dormancy, known as diapause. Diapause can only be broken when the proper environmental signal is received, such as a critical day length or a minimum period of chilling. until the diapause signal occurs, insects remain dormant and inactive.
Although it's only early August, I am already in fear of the cold. Call me what you like, as I am a southerner in blood...half latin indeed, so my broken spine will not enjoy those damp weeks, drizzly days, and unbroken cloudy months of but one degree.
I may be left in awe of the hibernating invisibles!!!

We hope that, when the insects take over the world, they will remember with gratitude how we took them along on all our picnics.

Hangs like a blue thread loosened from the sky.
