Peppered Moth, f. carbonaria and typical form - D Shenton

The Peppered Moth (Biston betularia) is a Geometrid in the subfamily Ennominae. This species is often an indicator of how polluted an area is, as white speckled ones show clean air, and darker ones show dirty air. The darker species is much rarer now, but the white form is common.

This species flies from May-August.
