The Oriental carpenter bee, Xylocopa nasalis, or Xylocopa (Biluna) nasalis, is a species of carpenter bee. It is widely distributed in Southeast Asian countries. It is a major pollinator within its ecosystem, and is often mistaken for a bumblebee. The species leads a solitary lifestyle with a highly female-biased colony in the nest.
Xylocopa nasalis is a member of the genus Xylocopa, first described in 1802 by French entomologist Pierre André Latreille. The genus name is derived from Ancient Greek and translates to ¨wood-cutter.¨ Xylocopa is comprised specifically of carpenter bees, who build their nests in burrows in dead wood, bamboo, or structural timbers. The genus is also related to the genus of Ceratina, which are referred to as ¨small carpenter bees."
Easily mistaken for bumble bees, carpenter bees of X. nasalis are relatively large, with a sturdy, black, lustrous body. Their thorax can exceed 5 mm in length, and some have yellow markings on their head. The front wing marginal cell is thin and stretched, while the apex, the anterior corner of the wing, leans away from the costa, which is the leading edge of the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green-Winged Bamboo-Carpenter sighting in Bangkok on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 160th most-seen of the 245 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.
June and October
In those months about 10% of wildlife watchers report a Green-Winged Bamboo-Carpenter in Bangkok on a given day, against under 5% in July–September and November–May, the lowest months. Those are among Bangkok's wettest months, with about 180 mm of rain a month against 10 mm in December.
9th of 9
Of the 9 cities where we can rate Green-Winged Bamboo-Carpenter sightings, Bangkok ranks 9th at under 5%. The best odds are in Phnom Penh (Cambodia, about 30%), Hanoi (Vietnam, about 20%) and Zhuhai [Macau] (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Green-Winged Bamboo-Carpenter is recorded against all the insects logged in Bangkok (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.
