Hypomecis is a genus of moths in the family Geometridae first described by Jacob Hübner in 1821.

Description

Palpi oblique, reaching beyond the frons and fringed with hair below. Forewings with slightly crenulate (scalloped) cilia. Vein 3 from near angle of cell and veins 7 to 9 from near upper angle. Typically with vein 10 and 11 arise from cell. Hindwings with vein 3 from near angle of cell. Cilia crenulate.^[1]

Ecology

Most of them are patterned cryptically and when they sit on bark, the markings appear like patches of lichen. Studies have shown that they choose the site for resting with care so that the pattern of crypsis is enhanced.^[2]
