Dragonfly Survey Underway in Delhi's Biodiversity Parks
Imagine tiny, colorful insects called dragonflies and damselflies.
Scientists and students in Delhi are counting these insects in several parks to see how healthy the environment is.
Dragonflies need clean water and places to hide to live.
They also help keep away mosquitoes.
This year's survey is looking at how the recent floods and rising temperatures affect the insects.
They are important to keep mosquito populations down, which helps with diseases like dengue.
Sadly, many dragonfly homes are disappearing because of pollution and climate change.
A three-day survey on dragonflies and damselflies is underway in Delhi's biodiversity parks.
The survey aims to assess ecosystem health and the impact of environmental changes.
Dragonflies are vital bioindicators and control mosquito populations.
Climate change and habitat loss pose threats to dragonfly populations.
Last year's survey showed decreased dragonfly diversity across parks.
