Ynghylch

The Emperor moth is a widespread, but never very common, moth of heathland, moorland, woodland rides, sand dunes and grassland scrub. A very large moth, the female can have a wingspan of up to 10cm, but the male is smaller, with large, feathery antennae. During the day, males can be seen flying swiftly about and can be mistaken for butterflies. The females rest in low vegetation during the day, releasing a special scent to attract males. The caterpillars feed on woody plants, such as heather, bramble and blackthorn, and overwinter as chrysalides, sometimes for two winters.
