Oxydia is a genus of geometrid moths in the family Geometridae, first described by Achille Guenée in 1857. Species in this genus are distributed across the Americas, with several species recognized as forest pests of economic importance. The genus includes defoliator species that attack conifers, eucalyptus, and other woody plants. Larvae are commonly known as loopers or measuring worms due to their characteristic looping gait.
