Bees in the genus Megachile (meaning “big lipped”) snip pieces of leaves to line their nests, giving them a common name of “leaf cutter” bees. Construction of each nest cell can take anywhere from 1.5 – 3 hours for Megachile sp. bees. (Wilson and Carril, p. 184 – 188)

European wool carder bees are native to Europe, Asia and North Africa. They were first observed near Ithica, NY in the 1960s and have since spread across north America. While native Anthidium sp. are active in the spring, only the introduced Anthidium manicatum is active in late summer.

Unlike most bees, the males are significantly larger than the females. Their eggs are laid at the back of the nesting tunnel, meaning that the smaller females hatch first. Large males defend flower patches and wait to mate with passing females.

Female wool carder bees collect the fuzz from plant leaves and use it to line their nesting areas and create dividers between their brood cells. (Wilson and Carrill, p. 176-178.)
