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.

Highlights:

*The scientists of Zoological Survey of India (ZSI) has revealed that Moths (Lepidoptera), which is widely considered as pests, are pollinators to a number of flowering plants in the Himalayan ecosystem.
*The study was carried out in states such as Arunachal Pradesh, Sikkim and West Bengal.
*The analysis of proboscis, a long and thread-like organ used to suck flower sap, of a dozen moth species’ revealed the presence of pollen grains.
*Scientists have pointed out that almost two-thirds of common large moth species have declined over the last 40 years in some parts of the world. One of the main reasons for the decline is light pollution.

Structure of Month Species:

*These structures are not only meant for sap sucking, but are morphological designed for pollination.
*Some species of moths, the organ is found to be modified into a spine like structure and in others, a lateral canal to arrest and disperse pollen.
*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.
*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.
