| Scarlet dragonfly | | The scarlet dragonfly (Crocothemis erythraea), or common scarlet-darter, is a species in the order dragonflies (Odonata), the suborder Epiprocta, the infraorder dragonflies (Anisoptera), the superfamily Libelluloidea, the family Libellulidae, and the genus Crocothemis. Subspecies of the scarlet dragonfly are Crocothemis erythraea chaldaeorum and Crocothemis erythraea erythraea. | | |
| | Females are light brown, olive brown, olive green or ochre in colour. The basal spots on their hindwings are yellow or yellow-orange. The wingspan of the scarlet dragonfly is 55 - 70 mm. Between the wing approaches a light narrow dorsal line can be detected. The pterostigma is yellow or orange-yellow to brown. Scarlet dragonflies can easily be confused with some darter species, however, they are larger and have a flatter abdomen than the darters. Young and female scarlet dragonflies are similar in colouration to female black-lined skimmers(Orthetrum cancellatum). The latter, however, have agrey to bluish marking on their wings. Female scarlet dragonflies also have a vertically protruding ovipositor. The legs are strongly built and are used to catch prey. | | |
| | | Scarlet dragonflies prey on insects (flies, mosquitoes), or on spiders, which they catch while in flight. They have their own territory which they defend against rivals. The mating season of the scarlet dragonfly is from May to August in Central Europe, and from April to October in the Mediterranean. Mating begins within a few seconds of flight and is usually continued on the ground. | | |

After hatching from their outer shell (exuviae), the adult dragonflies dry and begin to fly. In Central Europe, the scarlet dragonfly produces 1 new generation a year, in the Mediterranean, 2 are possible. | | |
