This species can be found in the Atlantic Coast of North America, up to New Brunswick, Canada. This population extends West as far as Ohio. There is a separate population in the Midwest, in Missouri and Arkansas. It is unknown whether there are continuous populations linking those on the Atlantic Coast and the Midwest. The tibialis subspecies is found only in North and South Carolina. The other populations are made up of only the subspecies C. b. bipunctata. It has declined significantly in parts of its range, more specifically in Ontario. Until recently, it was thought to be declining in New Brunswick as well, however new research has found it to be common in certain dune systems there. it is an under collected species, with scattered specimens. The species is not protected.
