IUCN RED LIST
Established in 1964, The IUCN Red List is a critical indicator of the health of the world’s biodiversity. Species are classified by the IUCN Red List into nine groups, through criteria such as rate of decline, population size and area of geographic distribution as:
- Extinct (EX) – This species is no longer extant
- Extinct in the wild (EW) – Survives only in captivity, or through cultivation often outside native range
- Critically endangered (CR) – In an extremely critical state
- Endangered (EN) – Very high risk of extinction in the wild
- Vulnerable (VU) – At high risk of unnatural (human-caused) extinction
- Near Threatened (NT) – Close to being endangered in the near future
- Least Concern (LC) – Widespread and abundant in the wild
- Data Deficient (DD) – Inadequate information to assess extinction risk
- Not Evaluated (NE) – Has not yet been assessed
The upper side of the male's wings is brilliant metallic orange with dark borders, while females are darker with orange patches. The underside is greyish-brown with fine lines and markings that provide excellent camouflage against bark and dry leaves.
The Indian Sunbeam is a fast-flying and alert butterfly that is often seen basking in sunny patches along forest paths and clearings. It typically rests with its wings closed, revealing a cryptic underside. Males are territorial and frequently patrol their preferred habitats in search of mates.
The Indian Sunbeam is a resident species and is not known to undertake long-distance migrations. Local seasonal movements may occur in response to rainfall, food availability, and habitat conditions.
Females lay eggs singly on host plants belonging mainly to the family Fabaceae. Breeding occurs throughout the year in tropical regions, with peaks during and after the monsoon season when host plants are actively growing.
The bright metallic orange upper wings are used in mate attraction and territorial displays, while the cryptic underside provides effective camouflage when the butterfly rests with closed wings. Rapid flight and erratic movements help evade predators.
Adults feed primarily on flower nectar and occasionally visit damp soil for minerals. Caterpillars feed on the leaves and young shoots of host plants, particularly legumes. The larvae may associate with ants, which provide protection in exchange for sugary secretions.
The Indian Sunbeam inhabits tropical and subtropical forests, forest edges, scrublands, wooded hillsides, plantations, gardens, and urban green spaces.
