Mniotype satura, the beautiful arches, is a moth of the family Noctuidae.

Forewing dull reddish throughout, more or less hidden by the purplish black suffusion; the upper stigmata, the basal patch, the submarginal area, and the subterminal line all dull reddish; the wedge-shaped marks before the last much shorter and less conspicuous; otherwise as in melanodonta; hindwing dark brownish-fuscous, with cellspot and slight outer line marked; a pale terminal streak at anal angle.

Larva reddish brown, darker along dorsum; dorsal line interrupted and obscure; spiracular yellowish green; an obscure subdorsal row of oblique grey streaks.

The moth flies from July to October depending on the location.

The larvae feed on various woody plants and deciduous trees.
