The ninebark calligraphy beetle is one of nearly 40 North American calligraphy beetles, named for the scrawly markings on their backs. Most calligraphy beetles require particular host plants. The ninebark calligraphy beetle feeds on ninebark (Physocarpus opulifolius).
Similar species: There are many calligraphy beetles that look quite similar. Identifying the plants they are eating helps identify the beetle. One species, for instance, is the dogwood calligraphy beetle (C. rowena), which eats dogwoods (Cornus spp.).
