Brachythemis leucosticta, the banded groundling or Southern banded groundling, is a species of dragonfly belonging to the family Libellulidae. It is found in Sub-Saharan Africa. Brachythemis leucosticta was first formally described as Libellula leucosticta in 1839 by the German entomologist Hermann Burmeister with its type locality designated as Port Natal. It was long considered that there was a single species, the banded groundling, but in 2009 they were split into two species; the Southern banded groundling (B. leucosticta) and the Northern Banded Groundling (B. impartita) with a wide area of overlap in central Africa.
Brachythemis leucosticta is a small species of dragonfly with a length of up to 33 mm (1.3 in) and a wingspan of up to 57 mm (2.2 in). The males have a completely black abdomen and thorax, pterostigmata which are bicoloured including yellow, a very dark brown or blackish band near the tip of each wing and a black face and eyes. The females have a yellow and black thorax and abdomen the colour becoming less bright in older individuals and they have brown banded eyes.

With luck
About 10% of wildlife watchers report a Southern Banded Groundling sighting in Nairobi on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 123 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November and December
In those months about 20% of wildlife watchers report a Southern Banded Groundling in Nairobi on a given day, against under 5% in January–April and June–October, the lowest months. Those are among Nairobi's wettest months, with about 100 mm of rain a month against 25 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Southern Banded Groundling sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 cities where we can rate Southern Banded Groundling sightings, Nairobi ranks 5th at about 10%. The best odds are in Antananarivo (Madagascar, about 50%), Kampala (Uganda, about 30%) and Harare (Zimbabwe, about 10%).
Same family: Libellulidae
The closest relatives of the Southern Banded Groundling that you can see in Nairobi (family Libellulidae, Skimmers) are Lucia Widow (about 10%), Orange-Winged Dropwing (about 10%) and Red-Veined Dropwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Banded Groundling is recorded against all the insects logged in Nairobi (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
