In terms of size, it has a wingspan of between 6 and 7 cm and a body length of between 4 and 5 cm. Regarding its distinguishing characteristics, in terms of coloration, the male is purple and the females and juveniles are yellowish and brownish.

It is a diurnal species, active during the hottest hours. It spends much of its time perched on dry branches, rocks, or plants in sunny locations. Males are highly territorial, defending small areas near water where they wait for females or hunt. They frequently return to the same perch after short flights. They hunt in flight thanks to their excellent vision and agility. They feed on small insects, such as mosquitoes and flies. They reproduce during the warmer months, between May and September. Mating occurs in flight in a position called "dragonfly heart". After mating, females lay their eggs in areas of still or slow-moving freshwater with plenty of vegetation. The eggs hatch after a few days or weeks depending on the temperature. The larvae complete metamorphosis in the water between 3 and 12 months, depending on food and temperature. They feed mainly on larvae of other insects and tadpoles. After emerging from the water, they attach themselves to a rock or plant where they undergo the final metamorphosis, giving rise to the winged adult, with wings and a hardened body. The winged adult phase lasts only a few weeks or months. During this time, they hunt, defend their territory, and reproduce.

In terms of interaction with humans, it is a harmless species, not stinging. It is important for pest control. It is sensitive to water pollution, and its presence is a good indicator of healthy aquatic environments, functioning as a bioindicator of good water quality.
