In 3 days ~40% in a week ~70%
Acisoma inflatum, the stout pintail is a species of dragonfly in the family Libellulidae. It's genus, previously thought to have two species, has been found out to have six unique species. The stout pintail and the slender pintail look very similar to each other upon a first look, and they often can be found in the same areas. The males have bright turquoise eyes and a base color of a pale blue that is heavily mottled with black patterns. Females still have some pale blue on them and also the black mottled patterns, but their abdomens and first couple segments of the thorax also have a yellowish-brown wash over them, making them duller than the males. Both males and females have a wide base of the thorax that quickly tapers off. They also both have long pterostigmata, but in males they are paler and more blue than in females, which have that same yellowish-brown wash over them.
Throughout much of Africa; relict populations exist north of the Sahara in Algeria, Egypt and Libya. It is found near and in calm water bodies with grass, such as grassy ponds and pans. Distribution overlaps with the similar Acisoma variegatum... Wikipedia →

Possible
About 20% of wildlife watchers report a Stout Pintail sighting in uMkhuze Game Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 59 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.
March
In that month about 40% of wildlife watchers report a Stout Pintail in uMkhuze Game Reserve on a given day, against under 5% in January and May–November, the lowest months. That is one of uMkhuze Game Reserve's wettest months, with about 80 mm of rain against 15 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Stout Pintail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only uMkhuze Game Reserve, in our data
uMkhuze Game Reserve is the only park on Wallace's Line with enough records to rate Stout Pintail sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Stout Pintail is recorded against all the insects logged in uMkhuze Game Reserve (5 verified sightings from 2019 to 2026), 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.
