Oak Lutestring Cymatophorina diluta

([Denis & Schiffermüller], 1775)

---

Wingspan 33-36 mm.

A species of mature oak woodland, the ones occuring in Britain are a separate subspecies, hartwiegi.

Like other lutestrings, it can be variable, and there is a relatively plain, greyish form.

The single generation flies in August and September, and the caterpillars, which feed on oak (Quercus), are dull greenish yellow with a black head.
