Ynghylch

The Noble chafer is a rare, metallic-green beetle that can be found in traditional orchards. The larvae live in old, decaying fruit trees, where they take up to three years to develop into adult beetles. Adults are on the wing for about six weeks from June to August, and feed on elders and umbellifers, such as Hogweed and Meadowsweet.

What to look for

Adult Noble chafers are metallic bronze-green, with white speckles. It can be confused with the Rose chafer (Cetonia aura), but has wrinkled wing cases; the Rose chafer has smooth wing cases.

Where to find

Mainly found in Worcestershire, Gloucestershire and Herefordshire, but also recorded in the New Forest, Oxfordshire and Kent.
