Oxyodes scrobiculata, the longan semi-looper or longan leaf-eating looper, is a moth of the family Erebidae. The common name "looper" is used despite looper moths generally being in the family Geometridae. The species was first described by Johan Christian Fabricius in 1775. It is found in the Indo-Australian tropics of India, Sri Lanka, Myanmar, China, Taiwan, east to Guam, Queensland, New Caledonia, Fiji, Samoa and Tonga. Wikipedia →

With luck
About 10% of wildlife watchers report a Longan Semi-Looper sighting in Tuen Mun on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 152nd most-seen of the 557 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Longan Semi-Looper in Tuen Mun on a given day, against under 5% in January to April, the lowest months. Those are among Tuen Mun's wettest months, with about 200 mm of rain a month against 20 mm in December.

GBIF citizen-science records
It is estimated from how often the Longan Semi-Looper is recorded against all the insects logged in Tuen Mun (30 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.
