Description
Appias lyncida is a medium‑sized pierid butterfly with a wingspan typically ranging from 55 to 70 mm. The dorsal (upper) surface of the wings is primarily creamy white in both sexes, with subtle brownish or chocolate‑coloured markings that give the species its common name. The ventral (underside) surface displays a more pronounced chocolate or brown hue, especially on the hindwings, where a series of faint, pale spots may be present. Sexual dimorphism is minimal, although females can sometimes exhibit slightly darker or broader markings than males.
Distribution
The species occurs across a broad region of South and Southeast Asia, including:
- Indian subcontinent (India, Sri Lanka, Bangladesh, Nepal, Bhutan)
- Myanmar and Thailand
- Peninsular Malaysia, Singapore, and Indonesia (Sumatra, Java, Borneo)
- Southern China (Yunnan, Guangxi)
Habitat
Appias lyncida inhabits lowland and foothill forests, forest edges, plantations, and gardens near wooded areas. It prefers sunny clearings and riverine corridors where host plants are abundant. The butterfly is often observed at elevations up to about 1,500 m, though it is most common below 800 m.
Life cycle and biology
- Egg: Laid singly on the underside of host‑plant leaves.
- Larva (caterpillar): The caterpillars are greenish with longitudinal stripes, blending with the foliage of their food plants.
- Host plants: Primarily members of the family Capparaceae, especially species of the genera Capparis and Crataeva.
- Pupa: Forms a green to brown chrysalis attached to the host plant or nearby vegetation.
- Adult: Emerges after pupation and feeds on nectar from a variety of flowering plants, including members of the families Asteraceae and Lythraceae.
Behavior
Adults are strong fliers and are frequently seen patrolling forest clearings or perching on low vegetation. Males often engage in territorial displays, flying in short, high‑speed circuits near preferred perching sites. Both sexes are attracted to moist substrates, where they may partake in “mud‑puddling” to obtain minerals.
Conservation status
The International Union for Conservation of Nature (IUCN) has not evaluated Appias lyncida as a separate species; it is generally considered to be locally common throughout much of its range. Habitat loss due to deforestation and conversion of forested land to agriculture may affect regional populations, but no specific threats have been documented that would place the species at immediate risk.
