Cicindela rufiventris varies considerably in the size and number of markings on the elytra. The key ID trait is the one alluded to in the scientific and common names: the red abdomen, visible most easily in a lateral (side-on) view. The red abdomen is also visible as the beetle flies though the air. The rear (apical) marks are always present, and another important trait is that this is a smaller beetle than most other tigers.
The adults of this species are typically active beginning in April, when they often hunt in areas of human disturbance: loading areas at logging sites, road cuts, and strip mine roads. The Eastern Red-Bellied Tiger Beetle has a range stretching from the lower Rio Grande Valley to Georgia and north to southern New York and New England.
