Lilioceris Lilii, the red lily beetle by Peter E Lynch
If you grow lilies or fritiillaries you will have this bright lacquered red beetle pest. I first saw lily beetles in my garden about 2014. They were more a curiosity, and after I found and killed the two of them, there was no sign the rest of the year. From then I would occasionally come across them doing no particular damage and delete them on sight.
