The usual form in rural areas is all white peppered with black dots on both the wings and body. Black forms known as f. carbonaria were once dominant in industrial areas with high levels of pollution although their frequency has been steadily declining in recent years. Intermediate forms known collectively as f. insularia are variable between the light and dark forms.
The larvae can be seen between early July and late September before they overwinter as pupae just below the ground.
The Peppered Moth is frequently found in UK gardens, yet its amazing story has made it famous all over the world. It's one of the best-known examples of evolution by natural selection, Darwin's great discovery, and is often referred to as 'Darwin's moth'.
