Rosemary Beetle, Chrysolina americana

Chrysolina americana

Twenty years ago you would be lucky to see this attractive metallic green and purple-striped beetle outside a greenhouse. The Rosemary Beetle Chrysolina americana was first discovered living outdoors in Surrey in 1994. Since then it has become widespread throughout southern England. They are commonly found on aromatic herbs, mainly rosemary but also on lavender, sage and thyme.

This one was found on rosemary whilst I was attending a course on bumblebees in Winchester, Hampshire.
