We have compiled ten reasons for the decline of dragonflies population in NorthEast India. Most of them are man-made causes.
1. Shrinkage of Water Bodies(Ponds, Lakes, Wetlands.
Dragonflies are usually found around water such as lakes, ponds, streams and wetlands because their larvae, known as ‘nymphs’, are aquatic.
As the water bodies are decreasing in NorthEast India, this hampering the population of Dragonflies.
2. Wide using of Pesticides and Fertilizers.
Another common problem is the usage of Pesticides and Fertilizers in excessive quantity. These chemicals then sip into the water bodies and destroying the habitat.
3. Insect’s population on which Dragonflies feed also depleting, as a result, they are depleting.
Dragonflies eat small insects that live in the water bodies particularly midges and mosquitoes.
4. Dragonflies are sensitive to the environment any changes in the environment affects their production.
10. Most important and burning environmental problem is the “Air Pollution”. Air Pollution causes the rise of temperature. Dragonflies need a minimum temperature to lay their eggs.
