Description


Sympetrum semicinctum can reach a length of 28–36 millimetres (1.1–1.4 in), with a wingspan of 45–55 millimetres (1.8–2.2 in). The male has a bright red abdomen with black markings on the lower sides and on the top of the segments 8 and 9, creating a U like pattern. The thorax is brownish red and the sides show three irregular black stripes. Face and eyes are dark red. The legs are black. The hind wings have a rusty patch at the base, covering one-third of the wings, while the front wings are almost completely transparent. Pterostigma is blackish red.

The female is mainly greenish-yellowish or orange, with red over green on eyes and extended blackish markings on the abdomen. Mature females sometimes turn red like males, while immature males are yellow like females and slowly reach their red coloration.




Biology and behavior


The flight period extends from April to mid October, but this dragonfly is more common in late summer.
Adults feed on soft-bodied flying insects. After mating females usually fly in tandem with males during oviposition, performed in flight by dipping the tip of the abdomen into the water. Larvae live in aquatic vegetation. They feed on many different aquatic insects (mosquito larvae, mayfly larvae, other fly larvae, small fish and tadpoles).
