Cool and breezy. A fly with a blue abdomen and golden thorax, first spotted yesterday, returns for further exploration of my partner’s knee.

The temperature rises and with it the insects: those that buzz, those that drift on filmy wings. Behind the trees, the blue ache of sky.

The sun makes a brief appearance; a breeze picks up. The bluebottle fly moves to the lee side of the railing and rubs its forefeet together.
