Scientists from the Zoological Survey of India have identified two new species of lichen moths from the eastern Himalayan region. The species, named Caulocera hollowayi and Asura buxa, were formally described by an Indian research team and published in the international taxonomic journal Zootaxa. The discovery adds to India’s documented moth diversity and marks the ecological importance of lesser-known insect groups in biodiversity-rich mountain habitats.
Species Identified in Eastern Himalayas
- Caulocera hollowayi was collected near Golitar in Sikkim.
- Asura buxa was found in Panijhora in West Bengal.
- The species were described by Navneet Singh, Santosh Singh and Srishti Bhattacharya.
- The names formally recognise the species as new to science.
Scientific Basis of Identification
- Researchers used wing colour patterns and banding to separate the species.
- Microscopic body structures were examined for taxonomic differences.
- Chaetotaxy, or the arrangement of tiny bristles and scales, was also studied.
- These features confirmed that the specimens belonged to previously unknown species.
Additional Findings in the Study
- The same research paper recorded seven more lichen moth species in India for the first time.
- This expands the known distribution of several moth species in the country.
- Such records are important for biodiversity inventories and conservation planning.
Ecological Importance of Lichen Moths
- Lichen moth caterpillars feed on lichens, which are highly sensitive to pollution.
- Lichens are often used as indicators of air quality and environmental health.
- The presence of lichen moths can help assess ecosystem condition in fragile Himalayan habitats.
- The discovery supports further study of Lepidoptera in biodiversity hotspots.
