Africanized honey bees (AHB) arrived in southern Utah at some point between 1994–2011, and have recently been implicated in the local extinction of Perdita meconis, a native specialist pollinator of the endangered Dwarf bear-poppy. Although AHBs were first detected in Utah in 2008, their presence in nearby states by 1998–2001 suggests that they may have been present much earlier. We refined the arrival date of AHBs in southern Utah by determining the ancestry of museum specimens collected between 2000–2008. We found AHBs in southern Utah from 2000 onwards, advancing the arrival date of this invader by at least 8 years. This lends credence to the hypothesis that AHBs played a critical role in the local extinction of P. meconis in Utah and highlights the importance of vouchering common species in collections to serve future research needs.
