and perching beautifully on my Hemp Agrimony (Eupatorium cannabinum)
(The frothy, pinkish flower clusters appear from July to September and are very attractive to all kinds of insects including butterflies like the Small Tortoiseshell and Red Admiral. Its common name comes from the resemblance of its leaves to Hemp or Cannabis, although it is not related to it. Another common name is “Raspberries and Cream”)
