Color and Appearance: Black with golden hairs

Pollen Collection: Hairs on face (Wilson and Carrill, p. 176-178.)

Flight Distance:

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.)

*From Wikipedia (

August 12, 2020: I have observed a lone wool carder bee flying loops around the anise hyssop patch. I presume that this is our resident male, defending his patch from interlopers and looking for mates. Although Wikipedia says that males will defend their patch against even humans, he seems to ignore me. I appreciate that.

According to Wikipedia: “These are based on hybrids within LiliumsectionArchelirion,[36][37] specifically Lilium auratum and Lilium speciosum, together with crossbreeds from several species native to Japan, including Lilium nobilissimumLilium rubellumLilium alexandrae, and Lilium japonicum.They are fragrant, and the flowers tend to be outward facing. Plants tend to be tall, and the flowers may be quite large. The whole group are sometimes referred to as “stargazers” because many of them appear to look upwards. (For the specific cultivar, see Lilium ‘Stargazer’.)” (
