Mompha jurassicella

(Frey, 1881)

---

Wingspan c. 12mm.

This rather local species, formerly known as M. subdivisella, occurs mainly in the south-eastern region of England, with a few records from surrounding counties.

The larval foodplant is great willowherb (Epilobium hirsutum), the larvae feeding internally in galleries in the stems during July and August.

There is a single generaion, the adult moths on the wing from September, hibernating over winter and appearing again up to April.
