I was brushing my teeth this morning. Then out of nowhere a fly flew across my face. WTF? It's December 28th. It's cold out. Why did a fly just appear out of nowhere, when I haven't seen one for a couple months? Has this ever happened to you?
I had to find out why this happens. Here's what I found out. Flies seem to appear in winter because they're hiding or dormant indoors, not truly gone; species like cluster flies invade homes in fall, clustering in walls/attics to survive cold, waking up on warm days, while others overwinter as eggs/pupae, hatching indoors when it warms, all thanks to natural "antifreeze" and strategic sheltering in warm, protected spots.
Warm indoor spots, even a crack in a window frame, offer enough warmth for some to stay active or hatch, making them seem to "just appear".
So they were never gone. And my house is clean. Really..... I guess it just goes to show, flies can live thru about anything.
That's why I asked this question. Could a fly live through a nuclear explosion? Here is the AI response: Yes, flies (especially fruit flies) have a decent chance of surviving a nuclear explosion's radiation because they tolerate much higher doses than humans, have small bodies reducing radiation absorption, and reproduce quickly, allowing for rapid adaptation, though survival depends heavily on distance from ground zero, as the initial blast's heat vaporizes everything. While not immune to the immediate fireball, insects generally fare better than larger animals in the aftermath's fallout, with species like fruit flies and wasps showing remarkable radiation resistance.
So moral of this whole story is: Don't freak out if you see a fly in the middle of winter or anytime you would think they shouldn't be there.
