Rare
Under 5% of wildlife watchers report a Nyctimenius tristis sighting in Singapore on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 621st most-seen of the 1045 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Nyctimenius tristis in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Nyctimenius tristis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Nyctimenius tristis that you can see in Singapore (family Cerambycidae, Longhorn Beetles) are Lebbek Borer (about 10%) and Epepeotes luscus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nyctimenius tristis is recorded against all the insects logged in Singapore (15 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.
