Altica is a large genus of flea beetles in the subfamily Galerucinae, whth about 300 species, distributed nearly worldwide. The genus is best represented in the Neotropic region, well represented in the Nearctic and Palearctic, but occurs also in the Afrotropic, Indomalaya and Australasia. The species are similar to each other, small metallic blue-green-bronze beetles, often distinguished from each other only by the aedeagus. The species of Altica, both as larvae and as adults, are phytophagous, feeding on plant foliage of various food plant taxa, specific for each Altica species. Onagraceae and Rosaceae (mainly Rubus) are the dominant host plant families for Holarctic species. The adult Altica beetles are able to jump away when approached.
