Context- Moths vital to pollination in the Himalayan ecosystem, finds study.
About The Study:
- Moths are widely considered as pests, but a recent study by scientists of Zoological Survey of India (ZSI) has revealed that these group of insects are pollinators to a number of flowering plants in the Himalayan ecosystem
- Under the project titled “Assessment of Moths ( Lepidoptera ) As Significant Pollinators in the Himalayan Ecosystem of North Eastern India”
- The study establishes 91 species of moths as potential pollinators of 21 plant families in Sikkim and Arunachal Pradesh in the northeastern Himalayas.
- The study revealed the importance of moths in nature.
- When we are sleeping in our bedrooms, they are tirelessly working for the ecosystems to work, on which our survival is invariably dependent, and are helping in a great way towards food security.
- Lepidoptera is the order of insects that includes butterflies, moths and skippers.
- The name Lepidoptera is derived from the Greek, meaning “scaly winged,” and refers to the characteristic covering of microscopic dust like scales on the wings.
- Due to their day-flying habits and bright colours, the butterflies are more familiar than the chiefly night-flying and dull-coloured moths, but the latter is far more varied and abundant.
- The skippers are a worldwide group intermediate between butterflies and moths.
- There are about 12,000 moth species in India and about 160,000 moth species in the world.
- About 90% of the world’s flowering plants are pollinated by animals. Therefore, pollinators are essential for the genetic exchange among flowering plants and the biodiversity among plants
- Researchers have pointed out that almost two-thirds of common large moth species have declined over the last 40 years in some parts of world.
- One of main reasons for the decline is light pollution (an increase in artificial light in moth habitats).
