This small creature just arrived (I didn’t see exactly how) on my computer screen. S/he ran to the top and walked along it from left to right (from my perspective).

Then s/he turned and came back the other way.

S/he displayed her/his wings briefly and then folded them under the wing cases again.

A moment later, s/he spread her/his wings again and flew off, too rapidly for me to see where to.
I am willing to guess it’s a beetle of some sort but that’s as far as my knowledge takes me! What fascinating companions we share the planet with!
It seems, then, that not all insect life dies off or becomes dormant in winter.
We recently had a fairly large spider on the ceiling but s/he disappeared after about 24 hours. I didn’t take a photo unfortunately but will try to do so if s/he (or another) reappears.
