Cicindela duodecimguttata is a widespread species found throughout eastern North America (except the extreme southeastern coastal plain and most of Florida) through the midwest and Great Plains to the Rocky Mountains. This species prefers wetter habitats near water, including muddy, sandy, or silty river and creek banks, muddy sections of sandy trails, and shores of some lakes (Pearson et al., 2015). It often occurs sympatrically with one or more different tiger beetle species within these habitats, but with each species favoring slightly different microhabitats. In Maryland, these species might include Cicindela ancocisconensis or Cicindela repanda. In Maryland, the species appears to occur primarily west of the Chesapeake Bay, locally from the Western Shore region, through the Piedmont to the mountains (Knisley & Schultz, 1997).
