Sympetrum semicinctum (Say, 1840) reaches a body length of 28–36 millimetres (1.1–1.4 in) and has a wingspan of 45–55 millimetres (1.8–2.2 in). Males of this species have a bright red abdomen with black markings on the lower sides and on the top of abdominal segments 8 and 9, which form a U-shaped pattern. Their thorax is brownish red, with three irregular black stripes along its sides. The face and eyes are dark red, and the legs are black. Hindwings have a rusty patch at the base that covers one-third of the wing, while front wings are almost completely transparent. The pterostigma is blackish red.

Mature females sometimes develop red coloration matching males, while immature males are yellow like females and gradually gain their mature red coloration.
