Wild UK Moths Diversity and Welfare

UK moth populations have declined significantly from habitat loss and light pollution affecting both individual welfare and ecosystem function.

Key Facts

UK larger moth species have declined by 28% since 1968 with more dramatic declines in southern England
Light pollution disrupts moth navigation, mating and host plant location causing population impacts
Habitat loss particularly of flowery meadows reduces caterpillar food plant availability
Some moth species are now restricted to nature reserves from agricultural intensification
Garden management for moths including native planting and turning off lights at night helps

Welfare Considerations

Moth welfare at population level is severely affected by light pollution and habitat loss. Individual moths disorientated by artificial light face exhaustion and predation. Reducing light pollution is a welfare intervention accessible to individual households and councils.

What You Can Do

Turn off or shield outdoor lights at night to reduce moth attraction and disorientation
Plant native flowering plants including evening primrose and night-scented stock for moths
Support Moth Conservation Trust and wider invertebrate conservation organisations
