Dragonflies and damselflies are declining in the UK due to habitat loss and pollution, with their welfare spanning both aquatic larval and aerial adult stages.
Dragonfly larvae in polluted or degraded water bodies face physiological stress and developmental failure. Adult dragonflies unable to find suitable territory near water cannot reproduce. While odonata sentience is uncertain, their ecological role and the welfare of insect-dependent species make dragonfly population welfare relevant. Clean water and wetland creation directly benefit dragonfly welfare.
