Young female, Kruger National Park



Description
By far the most common and widespread Ceriagrion species in Africa, the mature male has green eyes, the head and thorax (brownish) orange to bright yellow and the abdomen orange to red. It can always be recognised by S10 with raised processes on both sides of apical excision, each bearing several large black denticles; and also the paraprocts reach well beyond tips of cerci.
Small; wingspan 46 mm.
Male easily recognised as a citril species by its bright orange abdomen but only conclusively distinguishable Suave Citril by the presence of a small tooth on the hind margin of s10 (Suave Citrillacks these).
Female less easily identifiable as a citril, is uniformly pale olive to fawn, becoming orange with age, best identified by association with male.

Distribution
Widespread from South Africa to the Sahel.



Habitat
Standing and often temporary waters in open landscapes, open areas in forest or shaded by gallery forest. Usually with emergent and often aquatic vegetation.

Description
Very large, metallic greenish brown with large, rounded glistening wings which have dense and delicate net-like venation. The Glistening Demoiselle is distinguishable from all other damselflies in the region by its large size, sombre colouring, densely veined wings and large number (about 25) of Ax veins in fore- and hindwings.
Female: Club-like end of abdomen very conspicuous.

Distribution



Habitat
Rivers and streams, but possibly also flowing channels in marshes, shaded by gallery forest, but sometimes also in open areas in forest. Often with emergent vegetation, submerged roots, coarse detritus and/or probably overhanging branches.

Genus Sympretum Newman, 1833 (Darters)
Suborder Anisoptera. Superfamily Libelluloidea. Family Libellulidae

The genus Sympetrum has a species-rich occurrence in North America, Europe and Asia. There are only two species in Africa south of the Sahara, both of which also occur in South Africa. Sympetrum fonscolombii is a migrant, breeding in temporary pools. It is widespread in most parts of Africa, whereas S. navasi is very localised to swamp and large river habitats.
Darters are small- to medium-sized dragonflies. The males have a red abdomen. In both species the female is guarded in tandem by her mate when she lays her eggs by touching the water surface in flight. Characteristic features of the genus are the low number of antenodal veins (6.5–7.5 or even 8.5 in the forewing). It is currently under discussion whether the two species belong to the genus Sympetrum, since they may belong to two completely different genera. Hence, the genus names of both species may change.

Meaning of scientific name: The name is composed of the Greek sym-piézein – “to compress” and êtron – “abdomen”. Newman, the author of the genus, believed erroneously that a laterally compressed abdomen was characteristic of the genus.

Aged male, Kruger National Park, Satara (Feb 2021) © mposthumus

Identification
The male’s abdomen is scarlet and the thorax laterally red with a yellow or greenish-yellow spot. The hindwings are marked with a yellow basal spot. The pterostigma is yellow in both sexes.
Other species with a red body, broader abdomen and yellow basal wing spots are Crocothemis erythraea, C. sanguinolenta and Trithemis kirbyi.

Face: reddish brown. Labrum, frons and front of vertex reddish brown. Sides of postclypeus and frons, and back of vertex, yellowish or greyish brown.
Eyes: dark reddish brown above, greyish blue below.
Prothorax: with long setae giving appearance of a 'hairy collar'.
Synthorax: reddish brown, becoming greyer at sides, with two indistinct, diagonal grey to cream stripes. Sometimes only one of these stripes is visible.
Wings: with small orange splashes at bases, more so in hindwing. Veins reddish brown, particularly near thorax.
Pterostigmas: light yellowish brown between dark brown veins, 3.1-3.2 mm long. Membranule white.
Abdomen: usually orange-red, with two black dashes both in centre and at sides of S8-9. Some individuals distinctly more pale orange-brown than
orange-red.
Female: yellowish brown becoming greyish brown with age, with an indistinct, wide, pale greyish diagonal line on side of thorax. A fine black line along abdomen separates yellowish brown above from pale straw below.

Meaning of scientific name
Named in honour of the French entomologist ELJH Boyer de Fonscolombe (1772–1853), who described the species for the first time, but under a name that was occupied by another species.

Distribution
The species is widespread in Africa, Europe and western Asia.

Ecology and behaviour
Sympetrum fonscolombii is a migrant species that Southern Africa during the rainy season. It colonises all types of freshwater habitats. Development from egg to emergence takes less than 50 days and may be completed in as little as 35 days. The larvae are well adapted to dwell in rain pools of short duration. Due to its rapid growth, the species may complete several generations within a year. During egg-laying, the female is usually guarded by the male in tandem. With a dancing flight of the tandem, the female touches the water surface. Usually, the eggs are placed in open-water habitats with sparse vegetation.
The Red-veined Darter is common between September and May but most abundant Oct-Nov and a few individuals may be seen mid-winter.
