Simple Summary  The invasive hornet  Vespa bicolor  Fabricius was first discovered in Taiwan in 2003 and was not confirmed to have been established until 2014. This study was conducted in order to (1) assess the current status of  V. bicolor  abundance, dispersal, seasonality, and possible impact on honeybee ( Apis mellifera  Linnaeus) in Taiwan; (2) and to trace the origins of Taiwan’s  V. bicolor  population. To assess  V. bicolor  abundance, we used visual surveys, sweep netting, and hornet traps in four known ranges in northern and central Taiwan from 2016 to 2020. Additionally, to understand  V. bicolor  dispersion, we mapped environmental data using ArcGIS, and to predict future  V. bicolor  range, we used ecological niche modeling. The results show that  V. bicolor  has stable populations in three areas in northern and central Taiwan, and mainly preys on  Apis mellifera . Our analyses suggest samples from Southeastern China as having the closest relation in DNA sequences with Taiwan’s  V. bicolor  population. Due to the negative economic and ecological impacts of  V. bicolor  in Taiwan, our findings shed light on the value of monitoring and controlling its populations, rather than working exclusively towards elimination.    Abstract  The invasive alien species (IAS)  Vespa bicolor  is the first reported hornet that has established in Taiwan and is concerning as they prey on honeybee  Apis mellifera , which leads to colony losses and public concerns. Thus, the aim of this study was to assess the current status of  V. bicolor  abundance, dispersal, and impact and to trace the origins of Taiwan’s  V. bicolor  population. Our studies took place in five areas in northern to central Taiwan. We used mtDNA in the phylogenetic analyses. Field survey and ecological niche modeling (ENM) were used to understand the origins and current range of the invasive species. Two main subgroups of  V. bicolor  in the phylogenetic tree were found, and a clade with short branch lengths in Southeastern China and Taiwan formed a subgroup, which shows that the Taiwan population may have invaded from a single event. Evidence shows that  V. bicolor  is not a severe pest to honeybees in the study area; however, using ENM, we predict the rapid dispersion of this species to the cooler and hilly mountain areas of Taiwan. The management of  V. bicolor  should also involve considering it a local pest to reduce loss by beekeepers and public fear in Taiwan. Our findings highlight how the government, beekeepers, and researchers alike should be aware of the implications of  V. bicolor ’s rapid range expansion in Taiwan, or in other countries.
