  • Calligrapha pnirsa

    leaf beetle

    Calligrapha pnirsa is a species of leaf beetle in the family Chrysomelidae, found in North America. It is a univoltine species with adults emerging in spring to feed, mate, and oviposit on host plant foliage. Larvae develop through multiple instars feeding on leaves before dropping to the soil to pupate. New adults emerge in late summer, feed briefly, and overwinter to complete the annual cycle. Like other members of the genus Calligrapha, it exhibits strong host plant specificity.

It is part of a genus known for extreme host specificity, with most species feeding on a single plant genus. This species closely resembles Calligrapha spiraeae and Calligrapha rowena in appearance, but is distinguished by its association with hazel (Corylus spp.) rather than ninebark or dogwood. Like other Calligrapha species, it exhibits reddish coloration with small black spots on the elytra.

  • Calligrapha rowena

    Rowena's Leaf Beetle

    Calligrapha rowena is a species of leaf beetle in the family Chrysomelidae, found in North America.

    A leaf beetle in the family Chrysomelidae that is highly host-specific to ninebark (Physocarpus opulifolius). The species was described by Say in 1826 based on specimens collected from ninebark, which was then classified under the genus Spiraea—hence the species epithet spiraeae. Adults are reddish with small black spots on the elytra and are readily found on their host plant throughout the growing season. The species is notable among Calligrapha for its strict monophagy, utilizing no other known host plant besides ninebark.
