Light Pollution
I have a paper lantern light hanging in the window of my office. Every night moths flock to the window trying to get closer to the light, which they think is the moon.

It’s true: moths (along with many other night creatures like turtles and birds) navigate by the moon, and haven’t adapted to human light pollution. There are whole flocks of birds who get confused by city lights.

Sorry, mothies. It’s just my paper lantern.
