Rare
Under 5% of wildlife watchers report a Duolandrevus coulonianus sighting in Taipei on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 520th 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.
October and November
In those months about 10% of wildlife watchers report a Duolandrevus coulonianus in Taipei on a given day, against under 5% in December to September, the lowest months.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Duolandrevus coulonianus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Gryllidae
The closest relatives of the Duolandrevus coulonianus that you can see in Taipei (family Gryllidae, True Crickets) are Cardiodactylus guttulus (about 10%) and Beybienkoana karnyi (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Duolandrevus coulonianus is recorded against all the insects logged in Taipei (11 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.
