Scientific name: Diachrysia chrysitis
Two generations from June to July and August to September as far north as Yorkshire, the second generation being absent further north. Common and fairly frequent throughout Britain.
This unmistakeable moth has a spectacular brassy, metallic sheen on the forewings. There are two forms differing in the brown central cross-band which is complete in f. aurea but separated into two blotches in f. juncta. The adults feed at dusk at the flowers of Honeysuckle, buddleias and Red Valerian.
The larvae can be found from July to the following May feeding at night and hiding low down on the foodplant stem during the day. They overwinter as small larvae, near the ground amongst vegetation.
