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. | | |

| The thorax in both sexes is yellowish brown to olive-brown. The abdomen of the females isup to 34 mm in length and dark with a mesh-like pattern and 2 black bands running lengthwise. In older females the abdomen may turn blue (through coverage with wax). The 2nd to 7th abdominal segments of the older males (excreted by wax that adheres to the surface) are also a powdery blue. The abdomen of the males re... | | |

| ...The encrusted ocelli are at the front of the relatively small head. The antennae consist of 7 segments. The larvae overwinter twice in water and leave those on a plant stem, 2 to 3 years after they have hatched from their eggs. The new generation of black-lined skimmers hatch at the end of May. | | |

| ... lengths of 35 - 45 mm. Their bodies are bright red in colour. They have compound eyes. In the males, the upper part of the eyes is red in colour, while the lower part is whitish to yellow. In the females the eye colouration is paler. The thorax has black markings on its upper surface and on the sides. Young specimens of both sexes have yellow to bright red stripes on the surface of the middle segment of the thorax (mesothorax). In some females these stripes are paler - reddish-orange to yellow - and... | | |

| The large red damselfly has wing spans of 40 - 70 mm. Their pterostigma and the markings on their legs are solid black. Due to their external appearance, the large red damselfly can be confused with the small red damselfly (Ceriagrion tenellum). The latter, however, has red legs. Confusion with Pyrrhosoma elisabethae is also possible. Here differentiation is possibl... | | |

There are yellowish-brown to orange-brown bands of colour at the edges which on the top edge of the hind wings are extended in black bezel. The hinder area of the wings has the same markings. The hind wings have 2 short tails (spores) and a number of blue spots on the upper surface. The underside of both pairs of wings has a vibrant patchwork of stripes and spots. | | |
