Unidentified Altica leaf beetles sorted by host plant

To facilitate species-level identications of images in the undifferentiated Altica leaf beetles (Chrysomelidae) gallery, I sorted them by the apparent host plant captured in the photos (when identified by the submitter or determined by me where possible). Hopefully this compilation will be of assistance to experts examining the images of these phyto-specific insects.
