Rare
Under 5% of wildlife watchers report a Shrill Thorntree Cicada sighting in Kruger National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 290th 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 30%, if each day is a fresh chance.
November to February
In those months about 10% of wildlife watchers report a Shrill Thorntree Cicada in Kruger National Park on a given day, against under 5% in March to October, the lowest months. Those are among Kruger National Park's wettest months, with about 90 mm of rain a month against almost none in August.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Shrill Thorntree Cicada sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Shrill Thorntree Cicada sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Shrill Thorntree Cicada is recorded against all the insects logged in Kruger National Park (14 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.
