Rare
Under 5% of wildlife watchers report a Burmese Engrailed Moth sighting in Taipei on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 455th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Burmese Engrailed Moth in Taipei on a given day, against under 5% in March to December, the lowest months. Those are among Taipei's driest months, with about 90 mm of rain a month against 270 mm in June.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Burmese Engrailed Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Burmese Engrailed Moth sightings, Taipei ranks 3rd at under 5%. The best odds are in Hong Kong (China, about 10%) and Tuen Mun (China, under 5%).
Same family: Geometridae
The closest relatives of the Burmese Engrailed Moth that you can see in Taipei (family Geometridae, Geometer Moths) are Milionia basalis (about 20%), Eumelea ludovicata (about 10%) and Asian Cross-Lined Wave Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Burmese Engrailed Moth is recorded against all the insects logged in Taipei (13 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.
