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.
Calligrapha praecelsis
Calligrapha praecelsis is a leaf beetle species in the family Chrysomelidae, first described by Rogers in 1856. It belongs to the genus Calligrapha, a group known for their distinctive, often ornate elytral markings. The species is found in North America, with records from Manitoba, Canada. Very few observations of this species have been documented.
Calligrapha pruni
Calligrapha pruni is a leaf beetle species in the family Chrysomelidae, described by W.J. Brown in 1945. It is found in North America, with records from Ontario and Québec in Canada. Like other members of the genus Calligrapha, it is likely a host specialist, though specific host plant associations for this species are not documented in the provided sources.
Calligrapha rhoda
Calligrapha rhoda is a leaf beetle in the family Chrysomelidae, occurring in North America. 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. It is one of approximately 38 species in the genus Calligrapha, a group characterized by dome-like body shape and distinctive black and white or red coloration with variable elytral markings. The species is closely associated with hazel (Corylus spp.) as its host plant. It closely resembles C. spiraeae and C. rhoda but can be distinguished by its host plant association.
Calligrapha spiraeae
Ninebark Calligrapha Beetle
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.
Calligrapha verrucosa
Calligrapha verrucosa is a species of leaf beetle in the family Chrysomelidae. It is found in North America, with records from western Canada including Alberta, British Columbia, and Manitoba. As a member of the genus Calligrapha, it likely exhibits the characteristic dome-shaped body and distinctive elytral markings typical of the group, though specific morphological details for this species are poorly documented in the provided sources.
