About 10% of wildlife watchers report a Bloated Hedgehog Fly sighting in Johannesburg on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 120th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September–October and December–April
In those months about 10% of wildlife watchers report a Bloated Hedgehog Fly in Johannesburg on a given day, against under 5% in May–August and November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Bloated Hedgehog Fly is recorded against all the insects logged in Johannesburg (12 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.
