With luck
About 10% of wildlife watchers report a Birthamula rufa sighting in Hong Kong on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 319th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April–August and October
In those months about 10% of wildlife watchers report a Birthamula rufa in Hong Kong on a given day, against under 5% in September and November–March, the lowest months. Those are among Hong Kong's wettest months, with about 170 mm of rain a month against 25 mm in December.

Same family: Limacodidae

GBIF citizen-science records
It is estimated from how often the Birthamula rufa is recorded against all the insects logged in Hong Kong (31 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.
