Twilight is set in the Pacific Northwest.
In the four houses I’ve lived in Seattle, bugs were never an issue. I have no idea why (good thread idea) but in my 20 years, there have been no bug concerns. I don’t have any screens, and often enjoy a nice summer evening outdoors. Can’t do that in most of the other places i have resided.
my wag is the aliasing effect of a movie viewing a diffraction grating.
But I have never heard that, just my guess.
My house, in Alabama, doesn’t have screens, but it was built in the 30s and most of the windows are painted shut, and we pretty much never open the ones that aren’t. My father’s house, built a few years ago, does, though, but it has a ton of windows.

It’s pretty common here in San Fran, in my experience.
