Calligrapha knabi
This record describes Calligrapha knabi (species). Recorded family: Chrysomelidae. Recorded order: Coleoptera.
Identification and Appearance
can be distinguished from C. rowena (a similar dogwood-feeding species) by the apical part of the arcuate band connected to the sutural vitta (e.g., the posterior V-shaped spot connected to the black longitudinal area where the elytra meet, while free in C. rowena ) and by the conspicuous small roundish spots on the reddish part of the elytra (minute, sometimes missing in C. rowena ). ‒J.Gómez-Zurita, pers.comm. to =v= 14.vi.2013 the reddish tinge to elytra comes from the red hindwings folded beneath the elytra, which in this part are translucent --J. Gómez-Zurita, pers. comm. to =v=, 14.vi.2013

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Calligrapha knabi. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
