Rosemary Beetle Chrysolina americana (Linnaeus, 1758)
This is a stunning and beautiful beetle, showing a rainbow like colouration when viewed closely. Chrysolina americana is another invertebrate that has appeared in the UK only relatively recently. Despite its scientific name, this beetle does not originate from America, but was originally a southern European species. It first appeared in the UK in the 1990's and has steadily spread north since. Nottinghamshire's first records seem to have occurred in 2009 from sites in Nottingham and Newark. This was a beetle we had looked for during the last couple of years and our first record came when six adults were found in the courtyard of the old Edwinstowe Craft Centre, now home to the Sherwood Forest Trust on 01/06/11. The adults are around 8-9mm and can potentially be found on Rosemary, Lavender and other herbs.
