Hundreds of endangered three-tailed butterflies (Chinese three tailed swallowtail)

Hundreds of endangered three-tailed butterflies (Chinese three tailed swallowtail) endemic to China were spotted gathering in the wild near a creek in Tengchong, SW China's Yunnan Province, this is a very rare treat.

The Bhutanitis-thaidina is a species of butterfly that is found in the Himalayan regions of China, Bhutan and India. It is known for its large size and striking coloration, the wings are primarily black and have bright markings at the hindwings. The hindwings have three tails, which mimic the antennae of a wasp, this is believed to deter predators.

Adult butterflies feed on nectar from a variety of flowers, and the larvae feed on leaves from plants in the citrus family. The Bhutanitis-thaidina is considered to be endangered due to habitat destruction and over-collection for the butterfly trade. They are listed as near threatened by IUCN.
This means that their natural habitat is being destroyed and that they are being captured in large numbers to be sold as decorative items or for other commercial purposes, leading to a decline in their population.
