Small Dotted Buff Photedes minima
Wingspan 20-23 mm.
A fairly common species over much of the British Isles, occupying marshy localities, damp woodland and similar habitats.
The females are smaller than the males, and are more well-marked; the males are plain buffish with darker dots along the veins, and often show a slight glossy sheen.
The moths fly from June to August in a single brood.
The larvae feed on the stems of tufted hair-grass (Deschampsia cespitosa).
