Dragonflies and damselflies are sensitive indicators of freshwater habitat quality, and their conservation requires protection of clean ponds and waterways.
The welfare status of dragonflies under ethical consideration relates to their nociceptive capacity, which is less well characterized than in vertebrate species. As invertebrates, they fall outside most legal welfare protections. However, their conservation is important both ecologically — as indicators of water quality and as predators of other invertebrates — and as part of broader efforts to maintain biodiversity that underpins healthy ecosystems supporting many vertebrate species whose welfare is better understood. Habitat restoration for dragonflies benefits the entire freshwater ecosystem community.
