In Banasa dimidiata, the diploid number of chromosomes is 16 in both sexes.
Banasa dimiata is a colorful, phytophagous stink bug widely distributed and commonly found in the United States and Canada from Vancouver Island to California and Quebec to Florida. It is associated with trees and shrubs in a number of different families including Rosaceae, Ericaceae, Caprifoliaceae, Betulaceae, Fagaceae, and Pinaceae (DeCoursey 1963,Mc Pherson 1982).
Say (1831) originally described this species as Pentatoma dimiata, but LeConte (1859) emended the name to dimidiata. While some have accepted this emendation (Hoffman 2005), both names remain in use (Froeschner 1988).

Help create a portrait of California stinkbug diversity and distribution by submitting your observations.A field guide to some of the stink bug taxa found in Southern California is now available athttp://www.inaturalist.org/guides/887. Smartphone users can use iNaturalist apps, or use the Riverside NatureSpotter app (available free online for iPhone and Android devices); or upload data and image files directly to the project site. Hosted by the City of Riverside, California's Metropolitan Museum, verification of observations will be carried out by Museum staff, University of California-Riverside Entomology personnel, plus other entomologists and iNaturalist users.
Most stink bugs are large, easy to photograph, and their egg masses are conspicuous. As observations accumulate, iNaturalist creates a checklist of observed species for the project. These observations may also provide early detection of the spread of introduced pest species, such as the Brown Marmorated Stinkbug (Halyomorpha halys).
