Join the Arnold Arboretum for a late night learning adventure to discover the nocturnal invertebrates that are flitting about the Arboretum after hours. Naturalist Sam Jaffe will start the evening in the classroom with some introductory information about the life-cycles of moths and other night flyers. He’ll then lead the group outdoors for a moth lighting at which we will admire and study a variety of nocturnal insects. Back in the classroom, microscopes and other field guides will allow us to make clear identifications of these lesser-seen beauties.

Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...
