Abstract/Summary

The effect of the alien invasive ladybird Harmonia axyridis on British native species was quantified as the extent to which population trends were altered at a 1-km grid square level, and correlated with the degree of habitat and diet niche overlap each species has with the invader. Preliminary analysis demonstrated that both diet and habitat niche overlap were significantly correlated with the effect of H. axyridis on population trends, suggesting that the invader may be playing a significant role in the decline of the British ladybird fauna.
