Those who borrow the light.

A porch-light census by fictional naturalist Mara Venn, who counted what came to the bulb—and learned to switch it off.A moon-bearing transect by Mara Venn. The count is over; the night has become navigable again.

FIELD THEORY

The dorsal-light compass

The moon should stay above.

A moth does not fly toward the moon. It keeps the brightest part of the sky at a steady angle to its back. A nearby lamp turns that ancient rule into a tightening orbit.

In moonlight mode, our code-drawn visitors stop spiralling. They take long, nearly parallel transects across the page: not absence, but orientation restored. The change is gentler than disappearance—and more truthful.

Not “toward” the light. The insect keeps the brightest hemisphere overhead. Only a nearby source bends that rule into a fatal geometry.

A wing is not powder.

Each shingle is a modified hair: a tiny, ridged tile that holds colour, sheds water and slips free from a spider’s web. What looks like dust on a fingertip was architecture a moment earlier.

A warm, still hour after rain made the fullest sheet. Counts are fictional; the seasonal logic is not.

A note left beside the sugar jar

Wing dust on my fingers. I’m sorry.

I used to call that shimmer evidence. It was only evidence that I had held too tightly. Tonight, each visitor is counted where it lands. The lamp burns for forty minutes, then darkness gets the rest of the night.
