Appias panda

Appias panda was described by William Chapman Hewitson in 1869.¹ It belongs to the family Pieridae, subfamily Pierinae, and the genus Appias, which includes about 30 species known as albatross butterflies. The species name 'panda' refers to its black-and-white coloration, which resembles the giant panda (Ailuropoda melanoleuca).²

The upperside of the wings is predominantly white with black markings. The forewing has a black apical patch and a black band along the costa. The hindwing has a black border that is broader in females. The underside is similar but with more subdued markings. Sexual dimorphism is present: females have more extensive black markings and may have a yellowish tinge on the underside.

Appias panda is found in the Indomalayan realm, specifically in Myanmar, Thailand, Laos, Vietnam, and southern China (Yunnan, Guangxi).³ It inhabits lowland and montane forests, often near streams and rivers. Adults are usually seen in forest clearings and along forest edges, where they feed on nectar from flowers.

The larvae of Appias panda feed on plants of the family Capparaceae, such as Capparis and Crateva species.⁴ The caterpillars are gregarious in early instars and become solitary later. Pupation occurs on the host plant or nearby vegetation. Adults are strong fliers and are often seen in mixed-species aggregations at mud puddles.⁵

The species is univoltine or bivoltine depending on locality, with adults flying from March to November. It is a lowland species but has been recorded up to 1,200 meters above sea level.⁶

Appias panda is often confused with the closely related Appias albina, but can be distinguished by the shape of the forewing black markings and the presence of a black spot at the base of the hindwing costa. The species is not well studied, and its population status is unknown, but it is not considered threatened.³

In some local languages, the butterfly is called 'panda butterfly' due to its coloration, and it is occasionally featured in butterfly collecting guides. However, it is not a common species in collections, and its biology remains poorly documented.²
