Lomographa
Hübner, [1825]
Lomographa is a of geometrid in the tribe Baptini, erected by Jacob in 1825. The genus contains multiple distributed across the Palearctic region, with some extending into North America. The best-studied species is Lomographa bimaculata (-pinion Spotted), which has served as a model for genomic studies. moths are generally small with white or pale and distinctive dark markings.
