Bombus eximius is a species of bumblebee that belongs to the subgenus Melanobombus in the simplified subgeneric classification. It is found in the Southern, Eastern and Southeastern parts of the Asian continent. Bombus eximius is a very large species of bumblebee. The queens are 28–29 mm (1.1 in) long, while the female workers are 14–19 mm (0.55–0.75 in) and the male workers 18–19 mm (0.71–0.75 in). The color of the hair on the thorax is black, and that on the mid and hind tibiae and the basitarsus is orange. The bright coloration has also been described as "yellowish red" (via German: gelblichrot).
This species can easily be misidentified as Bombus flavescens. The close-up view of the face of Bombus eximius shows the oculomandibular distance (OMD), i.e., the distance between the compound eye and the mandible, to be 0.9–1.0 times the mandible breadth. The labrum, i.e., lips, have irregular lamella, but are mostly straight. The inner eye margin has scattered large punctures.
The species is relatively uncommon in low altitude areas between 450–1,200 m (1,480–3,940 ft) around the Sichuan basin area. It has been found in the Himalayan region, Myanmar... Wikipedia →

With luck
About 10% of wildlife watchers report an Orange-Legged Bumble Bee sighting in Hong Kong on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 255th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report an Orange-Legged Bumble Bee in Hong Kong on a given day, against under 5% in June to February, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Orange-Legged Bumble Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Orange-Legged Bumble Bee sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Apidae
The closest relatives of the Orange-Legged Bumble Bee that you can see in Hong Kong (family Apidae, Honey Bees, Bumble Bees, and Allies) are Asian Honey Bee (about 30%), Green-Winged Bamboo-Carpenter (about 10%) and Collared Carpenter Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orange-Legged Bumble Bee is recorded against all the insects logged in Hong Kong (40 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.
