Argent and sable moths or Rheumaptera hastata are day flying moths of the Geometridae family, with distinctive black and white colourings. They tend to live on wetlands and hillsides. The larvae spin together the leaves of their food plants (such as birch and bog myrtle) to form their cocoons. It was named argent and sable in 1778. Argent and sable refers to the heraldic color names for black and white. Their distribution is Holarctic.

The wings have a black ground colour with variable white pattern elements. A wider inner cross and a narrow basal cross line are typical. The dark midfield is traversed by white patches, which may be continuous. The outer cross line forms a wide white band, which usually has a row of black dots. In the black area of the margin is a wavy line broken into white stains, which forms an arrow - or spearhead-shaped element (hastata is Latin for spear-shaped). The fringes are black and white patched. The pattern of the hind wing is similar to the front wing. In some forms the black tone is reduced on a few black stains.
