Whats This one?
I enclose two pictures of a beetle which we found 4-5 of in a Russian Sage (Perovskia). They were iridescent gold with green stripes. Any Idea what they were? Regards
In addition to Russian Sage, the Rosemary Beetle feeds on its namesake rosemary as well as lavendar, thyme and sage. The beetle, though its scientific name is Chrysolina americana, is native to southern Europe and has extended its range to Britain, but we do not know from where you are writing. Here is a link with more information.
