Survey Finds Slight Decline in Dragonfly and Damselfly Numbers in Delhi Parks
A recent survey across seven Delhi Development Authority biodiversity parks recorded 11,154 dragonflies and damselflies, a slight decrease from 13,253 last year. Experts attribute this dip to erratic rains, dry conditions, and fewer water pools. The survey, conducted from September 17 to 19 with participation from University of Delhi students and experts, also noted two new species sightings: the Yellow-tailed Ashy Skimmer at Aravalli Biodiversity Park and the Blue Grass Dart at Yamuna Biodiversity Park. Officials emphasized the importance of clean wetlands for sustaining these insects.
