Slender Burnished Brass Thysanoplusia orichalcea
Wingspan 36-44 mm.
A rare immigrant species, which has occurred less than 100 times in Britain, most often around the southern coastal districts.
The most likely period for its arrival is between August and October, and it is most frequently encountered at light.
Abroad, the species is distributed in the Mediterranean and African regions, where the larvae feed on a number of herbaceous plants. It is sometimes imported accidentally as a larva with cut flowers.
