UK Moth Decline Habitat Conservation

The UK has lost 34% of its larger moth species since 1968, with habitat loss, light pollution, and pesticide use driving catastrophic population collapses.

Key Facts

The UK has approximately 2,500 moth species, far outnumbering butterflies
Since 1968, larger moth species have declined by 34% in England, with steeper losses in southern England
Moths are critical pollinators, particularly for night-flowering plants
Moth larvae are a key food source for bats, birds, and other insectivores
Light pollution disrupts moth navigation, mating, and feeding behaviour
Pesticide use reduces both moth numbers and the plants their larvae depend on
Habitat fragmentation prevents moth populations from recovering or recolonising suitable areas

Welfare Considerations

While individual moth welfare consciousness is still limited, moth population collapse has cascading welfare effects across ecosystems. Moths support the wellbeing of countless other species - from bats to cuckoos - that depend on them for food. Habitat restoration and light pollution reduction serve both biodiversity and the wellbeing of the wider ecological community.

What You Can Do

Create moth-friendly garden habitats with native night-flowering plants
Switch to directed, warm-spectrum outdoor lighting that minimises moth disruption
Reduce or eliminate pesticide use in gardens
Participate in the National Moth Recording Scheme to contribute to population monitoring
Support conservation organisations working on moth habitat creation and restoration
