Rare
Under 5% of wildlife watchers report a Tailed Smoky Blue sighting in Kruger National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 588th most-seen of the 748 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Tailed Smoky Blue in Kruger National Park on a given day, against under 5% in June to April, the lowest months. That is one of Kruger National Park's driest months, with about 10 mm of rain against 110 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Tailed Smoky Blue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Tailed Smoky Blue sightings, Kruger National Park ranks 2nd at under 5%. The best odds are in iSimangaliso Wetland Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Tailed Smoky Blue is recorded against all the insects logged in Kruger National Park (6 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.
