How altitudinal gradient affecting distributional pattern of pollinating Hover flies along the agro-climatic zones of Himachal Pradesh, India

The present study over a period of 4 years has mapped down the status of pollinating hoverflies across the entire elevational stretch across the state. So for long-term monitoring, this distribution data which was not available previously, recorded during the recent study is believed to be beneficial. The study has shown that the distributional trend of the pollinating hoverflies along this wide elevational range follows the rules of monotonal declination of species richness along with increasing altitude.
