Appearance
Like other members of the genus Calligrapha, this species has intricate markings that resemble hieroglyphics.
Reproduction
Robertson (1966) reported that in some colonies the two sexes were present in roughly equal numbers, but that another colony yielded 3 males and 52 females, while yet another was home to 4 males and 12 females. In some species of Calligrapha males are unknown, and these species reproduce by parthenogenesis. In the case of Calligrapha alni a parthenogenetic colony may exist side-by-side with a colony that has both males and females and reproduces sexually.
