true spreadwings
Synonyms:
- scientific: Africalestes Kennedy, 1920; Paralestes Schmidt, 1951; Xerolestes Fraser, 1951; Icterolestes Pinhey, 1980
Type species: Agrion barbarum Fabricius, 1798
Introduction
Cosmopolitan, with over 80 species worldwide and fourteen in the Afrotropics: it is possible that once phylogenetic studies are done that African species will move to now unused genera like Africalestes, Paralestes and/or Xerolestes. All species typically perch with abdomen hanging and wings half-open. They are fairly small to fairly large (hindwing 17-29 mm), rather dull and inconspicuous damselflies, although often with distinctly blue eyes. Most species breed in standing waters, often seasonal, small and/or densely vegetated, but may be found far from water. Mostly in open areas, L. ochraceus, L. pinheyi, L. tridens and L. uncifer favour more marshy habitats, L. plagiatus likes streams, L. ictericus ephemeral pans, and L. dissimulans and L. virgatus are more often in or near forest (the latter often at higher elevations), while L. pallidus may also be found in very dry regions. Many species are variable in coloration, from a plain pale colour with some scattered dark markings, to completely dark. Dark markings often have a bronze sheen, but only two species are truly marked metallic green. Moreover many species develop thin whitish pruinosity on (parts of) thorax and abdomen. The relative size of the pterostigmas can be useful, but the measurements given below are approximate. Identifications must be made with all this variation in mind.
