Norfolk status Widespread. Two striking brassy metallic bands on forewing. Typically these two bands are separated, however the form tutti has the two vertical brassy bands on the forewing joined forming an H-shape.
The separate banded and H-shape banded forms are both the same species.
Diachrysia stenochrysis A controversial species named Diachrysia stenochrysis also has the two vertical brassy bands on the forewing joined forming a “H-shape”. It is suggested that the join needs to be at least 3 millimetres wide for it to be considered D stenochrysis. The species has not been clearly distinguished externally and genitally from D chrysitis.
Please note: Diachrysia stenochrysis has not been proven to occur in the UK.
