Striking brassy metallic bands on its forewings, typically these two bands are separated. The form tutti has the two vertical brassy bands on the
forewing joined forming an “H-shape”.
A valid separate species named Diachrysia stenochrysis also has the two vertical brassy bands on the forewing joined “H-shape”. It is thought that the "H" needs to be at least
3 millimetres wide for it to be considered stenochrysis.
Please note: It is not yet established that Diachrysia stenochrysis occurs in the UK.
