The Maiden's Blush moth has a reddish hue and a bold red line.

It has a more flecked background and wavy red line than the similar Blood Vein moth, with a black-bordered edge

The Blood Vein moth has a yellowish background flecked with grey like the Maiden's Blush and also a bold red line.

Instead of the two rows of black dots it has a lower grey wavy line; the bold red line is straight, forming either a straight line or slight V when the moth is at rest and the lower edge is continuous crimson/pink rather than broken black.
