Possible
About 30% of wildlife watchers report a Trimen's Knob sighting in Ankarafantsika National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 31 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 70% of wildlife watchers report a Trimen's Knob in Ankarafantsika National Park on a given day, against under 5% in October to December, the lowest months. That is one of Ankarafantsika National Park's driest months, with almost no rain against 560 mm in January. February and March have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Trimen's Knob is recorded against all the insects logged in Ankarafantsika National Park (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.
