Chalcostephia is a monotypic genus of dragonflies in the family Libellulidae containing the single species Chalcostephia flavifrons. It is known by the common names yellowface and inspector. It is native to central Africa, where it has a widespread distribution. This dragonfly lives in swampy habitats. It is affected by the drainage and reclamation of swamps for agriculture, but it is not considered to be threatened.
Chalcostephia flavifrons is a fairly small species of dragonfly, with a hind-wing length of 24 to 29 mm (0.9 to 1.1 in). The mature adult male is a bluish-grey colour and pruinose (covered with a dusting of wax particles on top of the cuticle). The adult female and the newly emerged male are dark with bold yellow banding. Both males and females can be distinguished from other similar species by their yellow face contrasting with the flattened, metallic green frons (front of the head).
The membranous, veined wings are transparent except for the pterostigmata, a small group of thickened cells at the leading edge of the wing-tips, which have pale centres and dark edges. This species has a widespread distribution over tropical... Wikipedia →

Possible
About 20% of wildlife watchers report an Inspector sighting in Kampala on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 42 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June, September and December
In those months about 30% of wildlife watchers report an Inspector in Kampala on a given day, against under 5% in February, April, July and October–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Inspector sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Inspector sightings, Kampala ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Ouagadougou (Burkina Faso, about 20%).
Same family: Libellulidae
The closest relatives of the Inspector that you can see in Kampala (family Libellulidae, Skimmers) are Southern Banded Groundling (about 30%), Violet Dropwing (about 30%) and Skylight Flutterer (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Inspector is recorded against all the insects logged in Kampala (15 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.
