Fused Burnished Brass Diachrysia stenochrysis
A controversial species which 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 cannot be reliably distinguished externally, differences in genitalia are extremely slight and DNA bar-coding remains inconclusive.

Please note: Diachrysia stenochrysis has not yet been included in the British list.
