European wool carder bee

European wool carder bee, Anthidium manicatum, is an exotic bee fairly recently detected in the western United States. Where it has established, it can often be found around lambs ear, Stachys byzantina, which has fine woolly hairs on the leaves which the female bees collect to line their nests. The male bees are very territorial and aggressively defend their favorite plants from other bees by bumping into the other bees. In addition to lambs ear, the bees may be found on catmint and Salvia sp.

The long-term impact of this introduced bee has yet to be determined. There is concern that introductions of exotic bees may increase the risk of new bee diseases to the US. The bees were first detected in New York in 1963 and were detected in California in 2007, and have since been found in Washington (2011) and Oregon (I have images of these bees from June 2009 in the Portland Metro area)
