Cicindela duodecimguttata Dejean
Cicindela duodecimguttata Dejean Distribution in North Dakota
Identification: Body size medium, about 12 mm to 14 mm in length. Dorsal surfaces of head and prothorax dark. Dorsal surface of elytra dark brown with light markings. Humeral lunule broken or complete and widely separated from marginal line. Middle band and apical lunule complete. Labrum unidentate. Clypeus glabrous. Frons and genae with erect setae. Antennal scape with three sensory setae.
Remarks: 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 (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).
Habitat: Occurs on open areas, usually with dark soils, in riparian areas throughout the state.
North Dakota Distribution: Statewide.
Season: A spring/fall species. In North Dakota, museum records indicate that adults are most active in May and June, and again in August and September.
