Rare
Under 5% of wildlife watchers report a Burmese Engrailed Moth sighting in Tuen Mun on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 492nd most-seen of the 557 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.
April–May and July
In those months about 10% of wildlife watchers report a Burmese Engrailed Moth in Tuen Mun on a given day, against under 5% in June and August–March, the lowest months. Those are among Tuen Mun's wettest months, with about 180 mm of rain a month against 20 mm in December.

GBIF citizen-science records
It is estimated from how often the Burmese Engrailed Moth is recorded against all the insects logged in Tuen Mun (5 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.
