Anthidium love gardens. They are strongly-marked yellow and black bees, exotic to North America, having been introduced in the mid 20th century. This group nests above ground either in plant stems or cavities in trees, walls, or even buildings. Named for their habit of lining nests with cottony plant fibers that females scrape or “card” off of leaves with fine mandibular teeth. Despite their name, Anthidium also use leaves, trichomes, and resin to line their nests. Two species are well established in the east–Anthidium manicatum and Anthidium oblongatum.
