I don’t know that I’d call this a serious pest but it certainly does make our garden look worse this time of year. This little bug has been here in pretty good numbers in recent years and they suck the juices out of some of our plants, making their leaves brown and desiccated. It generally doesn’t do the plant irreparable harm but it doesn’t do it much good, either. In past years I spray them and cut them off before they do their worst. This year I never got around to it and the damage is pretty well done at this point. They’re pretty, little things, I admit. But pests, nonetheless.
