Moth Conservation: Nocturnal Insect Welfare and Light Pollution

Overview of moth welfare, light pollution impacts, and habitat conservation for nocturnal insects.

Key Facts

UK moth populations have declined by 25% since the 1970s
Light pollution attracts and disorients moths, causing welfare harm and population impacts
Loss of wildflower grassland and woodland habitat reduces moth diversity
Moths are important pollinators and food sources for bats and birds
Moth-friendly lighting and dark sky initiatives reduce light pollution welfare impacts

Welfare Considerations

Moth welfare in 2026 is shaped by habitat loss, light pollution, and climate change. Light pollution attracts moths to artificial lights where they are exhausted, disorientated, and vulnerable to predators. Using wildlife-friendly lighting and participating in dark sky initiatives reduces this welfare harm. Habitat restoration and reduced pesticide use address the broader drivers of moth population decline.

What You Can Do

Switch outdoor lighting to wildlife-friendly amber LEDs or motion sensors
Plant caterpillar food plants to support moth breeding in gardens
Support dark sky reserve initiatives and light pollution reduction campaigns
