Rosemary Beetle

By Jules

Why did natural selection result in some very destructive, if very attractive insects surviving with the sole intention in life to eat my plants. In the brief respite between rain showers, I spotted these lil' critters all over my lavender bed. Oh they're very pretty – shiny like an oil droplet – but in high numbers they're not good. I've yet to discover who their natural predator is, and why those lovely colours evolveved to be on their wingcase. It must either be camouflage or a warning to potential predators. Anyway, despite them not being particularly welcome on my lovely flowering lavender, I don't use chemical sprays and so figured that as long as there weren't too many of them, then I could live with them. So, I took a few photos and then...how shall we put this?...streamlined the population numbers. :)
