2002. Miller, SR, R Gaebel, RJ Mitchell, M Arduser. Occurrence of two species of old world bees, Anthidium manicatum and A. oblongatum (Apoidea: Megachilidae) in northern Ohio and southern Michigan. Great Lakes Entomologist 35:65-69.
SUMMARY
Anthidium manicatum and A. oblongatum are two European bee species that have recently established themselves in North America. Anthidium manicatum has previously been documented in New York and Ontario, Canada, and A. oblongatum has been documented in New York, New Jersey, Maryland, and Eastern Pennsylvania. We surveyed a number of sites in Ohio, Michigan, and Indiana for these species in 2000 and 2001, and found both bee species to have extended their ranges into northern Ohio, and A. manicatum to have moved into southern Michigan. We present a key identifying the four Anthidium species now known from Northeastern North America.
