Perizoma minorata, the heath rivulet, is a species of moth of the family Geometridae. It is found in most of Europe

The wingspan is 16–20 mm.[It] is another inconstant species and shows some local and some individual minorata. variation. The name-typical form, as it occurs in the Alps, the mountains of Germany, Austria, S. France, etc., is the larger, paler race, the ground-colour being clear white, the markings often pale,the distal area at times with only quite weak dark shading. Hindwing whitish or very pale grey. - ericetata Steph., the only form known to me from Scotland, is considerably smaller, darker-marked, the white band - distally to the median generally with a sharper dividing-line, the hindwing darker grey. - norvegica Prout, from Norway, is as small as ericetata but otherwise forms a strong contrast to it, being more weakly marked than the name-type. — ab. monticola Strand is a rare aberration, with the median area not darkened at all, but only indicated by the lines which limit it. Mentioned from Norway and Scotland.[2]

There is one generation per year with adults on wing from the end of June to August.

The larvae feed on Euphrasia species. They feed on the developing seeds. The larvae can be found from August to September. It overwinters as a pupa.
