With luck
About 10% of wildlife watchers report a Wide-Armed Mantis sighting in Pretoria on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 107th most-seen of the 274 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Wide-Armed Mantis in Pretoria on a given day, against under 5% in May–June and September, the lowest months. That is one of Pretoria's driest months, with almost no rain against 130 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Wide-Armed Mantis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Wide-Armed Mantis sightings, Pretoria has the highest daily chance: about 10%. Next come Durban (South Africa, under 5%).
GBIF citizen-science records
It is estimated from how often the Wide-Armed Mantis is recorded against all the insects logged in Pretoria (14 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.
