Rare
Under 5% of wildlife watchers report a Dolbina formosana sighting in Taipei on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 570th 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
In that month about 10% of wildlife watchers report a Dolbina formosana in Taipei on a given day, against under 5% in February to December, the lowest months. That is one of Taipei's driest months, with about 95 mm of rain against 270 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Dolbina formosana sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Dolbina formosana sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Sphingidae
The closest relatives of the Dolbina formosana that you can see in Taipei (family Sphingidae, Sphinx Moths) are Green Pergesa Hawkmoth (about 10%), Marumba cristata (about 10%) and Yam Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dolbina formosana is recorded against all the insects logged in Taipei (9 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.
