Kew Arches Brithys crini
Kew Arches appears on the British list due to a number of larvae found feeding in Kew Gardens in 1933, and believed to have been introduced with imported plants, and subsequently reared to adulthood.
The species occurs in Europe and also in South Africa and Japan, as well as parts of Australia.
It can be a pest in some parts of its range, the larvae boring the stems and feeding on the leaves of lilies, mainly of the family Amaryllidaceae.
The adults are relatively nondescript brown moths and may be found on the wing in July in Europe.
