Emperor moth (Saturnia pavonia) is a moth that is also active during the day. The butterflies have a distinctive “eye” on their wings. Females are slightly larger than males and have a wingspan between 5 and 9 cm. This makes the emperor moth one of the largest butterflies in Europe. Emperor moths are found in hedgerows, thorn scrub, downland and open woodland.
Host plants include birch, pedunculate oak, willow, aspen, heather, blackthorn and blackberry. The striking caterpillars initially live in groups; as they grow larger, they disperse among the host plants.
The emperor moth overwinters as a pupa in a cocoon attached to a plant just above the ground.
