Xylocopa tenuiscapa
In 3 days ~30% in a week ~60%
Xylocopa tenuiscapa is a species of carpenter bee found only in South Asian and Southeast Asian countries. Like most bees, X. tenuiscapa has a diurnal activity cycle, but in the Western Ghats of Southern India, the species flies in moonlit nights and has been observed as pollinator of nocturnally flowering trees. Males of the species perch on exposed sites close to nests or in the landscape waiting for occasions to mate.

With luck
About 10% of wildlife watchers report a Slender-Scaped Carpenter Bee sighting in Sinharaja Forest Reserve on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th most-seen of the 117 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Slender-Scaped Carpenter Bee in Sinharaja Forest Reserve on a given day, against under 5% in February, April, June–July and September–December, the lowest months.

GBIF citizen-science records
It is estimated from how often the Slender-Scaped Carpenter Bee is recorded against all the insects logged in Sinharaja Forest Reserve (7 verified sightings from 2019 to 2026), 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.
