Nothris congressariella

(Bruand, 1858)

---

Wingspan c.15-20 mm.

An extremely localised species, occurring only on the Isles of Scilly and a few localities in Cornwall, and on Lundy (Devon).

The larva feeds between spun leaves of balm-leaved figwort (Scrophularia scorodonia), the foodplant itself being very localised and hence dictating the distribution of the moth.

There are two generations, moths being on the wing from May to July and again from September to October.
