General Description

This large and fairly robust geometrid moth that mimics wilted leaves with its jagged, rust and brown wings. Ground colour rust-tan with brighter rust shades at the wing margins, and a pinkish white shade along the forewing costa; and with three dark brown transverse lines. Very similar to S. kentaria, but in general slightly smaller and darker rusty browns (more yellow-brown in kentaria; alciphearia has the PM line straighter on both wings (best seen on the underside). S. kentaria usually has a jagged or wavy forewing PM line with a more pronounced indentation midway, and the hindwing PM line is more irregular and slightly curved outwardly (straight or nearly so in alciphearia). Some specimens may be impossible to determine without examining the genitalia (see McGuffin, 1987).
