A dark jewel met on a summer road in Medog.
On 28 June 2026, in the hills of Gelin Village, Beibeng Township, Medog County, Nyingchi, Tibet, I came across this compact scarab. It held still on a pale surface at the roadside, letting me get close enough for a few careful frames before it was gone.
The beetle is a flower chafer of the genus Heterorhina (family Scarabaeidae, subfamily Cetoniinae, tribe Goliathini). The identification currently stands at genus level and is awaiting community confirmation for the exact species. The genus name Heterorhina was established by Westwood in 1842, and its members are best known from tropical Asia.
In the photos the beetle shows a dark, stocky body: a broad pronotum, smooth and slightly glossy elytra that cover the abdomen, and sturdy legs typical of a chafer. Cetoniine adults are strong fliers, regularly drawn to flowers, sap, and ripe fruit, while their larvae develop in decaying wood and organic matter. Medog sits at the eastern end of the Himalaya, a pocket of wet forest famous for its insect diversity, and a fitting home for a flower chafer.
Flower chafers are sometimes called the jewels of the scarab family, and many relatives shine in metallic green or gold. This one wears a subdued dark coat, a reminder that even inside a glamorous tribe, plenty of species keep things quiet.
请问这篇文章里说鉴定暂时只到属级，不知道后来有没有确认到具体物种？另外想请教一下，这类花金龟在墨脱一般主要在什么环境下碰到，是访花比较多，还是像文中说的一样在路边吸食树汁或者腐烂果实？
还没确认到种，这条记录目前仍停在属级 Heterorhina，iNaturalist 上社区也还没有人给出种级鉴定，所以文章也就维持属级了。如果后续有专家确认到具体种，我会更新文章。
花金龟这一类成虫本身是典型的访花类群，常被花蜜、树汁和熟果吸引，飞行能力很强；在马路边碰到其实很常见，尤其是浅色路面和开阔处，它们飞累了或路过时会停下来歇脚。墨脱那种湿热林子里，访花（比如开花的乔木上）和路上偶遇都是常见场景，两者并不矛盾。文章里写的是当时在路上遇到它，只是记录现场情况，不代表它们主要待在路上。
