Cicindela repanda repanda Dejean Distribution in North Dakota
Identification: Body size medium, about 11 to 12 mm in length. Dorsal surfaces of head, prothorax, and elytra dark brown. Elytral markings white. Humeral lunule complete. Middle band complete. Apical lunule complete. Marginal line connected to or only very slightly separated from humeral lunule. Labrum unidentate. Clypeus glabrous. Frons and genae setose. Antennal scape with three sensory setae, otherwise glabrous or with one or two accessory setae.
Remarks: North Dakota specimens of C. repanda belong to the nominate subspecies C. repanda repanda Dejean. C. duodecimguttata can easily be confused with C. repanda. In C. duodecimguttata, the length/width ratio of the pronotum is 4 units long to 6 units wide and the front angles of the pronotum are sharp. Also in C. duodecimguttata (and perhaps an easier character to recognize), the humeral lunule is almost always widely separated from the marginal line (i.e marginal line not well developed anteriorly). In C. repanda, the length/width ratio of the pronotum is 4 units long to 5 units wide and the front angles are more rounded. The humeral lunule in C. repanda is connected to or only slightly separated from the marginal line (i.e. marginal line well developed anteriorly). See remarks on C. duodecimguttata for comments on other similar species.
Habitat: Moist sandy soils and mudflats along riverbanks.
North Dakota Distribution: In suitable habitat statewide.
Season: A spring/fall species. Adults are most active in May and June, and again in late August and September. Individuals have been collected throughout the summer.
