Moth at the window
A moth at the window after dark is a visitor from the night shift: most moths work while you sleep, so the sight can point to the unseen effort around you. Yorkshire folk called white night moths "souls."
What it may mean
Moths do most of their living while people sleep. North America has more than ten times as many kinds of moths as butterflies, and on warm nights they are out pollinating pale, scented flowers, feeding bats and owls and laying the eggs of next year's caterpillars. The moth pressed against your window screen is a small delegate from that night shift. It can be your cue to notice the work that happens out of sight in your own life: the neighbor who plows the road at 4 a.m., the parent who packs lunches after everyone is in bed, the effort you put in that nobody sees.
Depending on how you saw it
Clinging to the window screen
Moths gather on lit windows and screens on warm nights, held there by the light inside. From the other side of the glass, you are the bright thing they cannot leave. Who is drawn to you more than you realize, and are you giving them anything they can use?
A luna moth by the porch light
The pale green luna moth has no working mouth as an adult and lives only about a week on energy stored as a caterpillar. Everything it needs, it gathered earlier. What reserves built in an earlier season are you living on now, and are they enough?
A moth asleep on the wall by day
Many moths spend the day resting in plain sight on bark or a wall, trusting their colors to make them disappear. You may walk past one for hours. What has been right in front of you, waiting to be seen, simply because it does not move?
A moth that hovers like a hummingbird
Some day-flying sphinx moths, such as the hummingbird clearwing, hover at flowers and are often mistaken for tiny hummingbirds. A second look shows antennae and no beak. What have you assumed about someone because of the way they move through a room?
Why it happens in nature
Moths and butterflies belong to the same insect order, but moths far outnumber them, and most fly at night. They circle lamps because they keep their backs turned toward the brightest light, a habit that works under the open sky and traps them near a bulb. The moths that eat clothes are a few small species whose larvae feed on wool; the large ones at the window are not among them.
