General Description

provided by University of Alberta Museums
This species is similar to Cicindela repanda . However, it is more closely related to C. oregona and hybridizes with it in a realtively wide zone along the Rocky Mountain Foothills of Alberta. Populations of C. duodecimguttata occur east of the foothills and populations of C. oregona to the west along mountain valleys. Hybrid populations have markings intermediate to those of C. oregona and C. duodecimguttata. The humeral lunule may be narrowly broken or expressed as a spot and the marginal line is of variable length.
