  • North American Hornet Screening Tool Now Available

    • Jun 21, 2021

    • USDA. APHIS. PPQ. CPHST. Identification Technology Program.

    • ITP is pleased to announce the release of North American Hornet Screening Tool. Hornets in the genus Vespa play a critical role as predators in their native habitats, but in North America these species may have a disastrous impact on agriculture by reducing populations of important pollinators such as the honey bee. Hornets also pose a serious health risk to humans because of their powerful sting. North American Hornet Screening Tool is designed for anyone who may encounter these species in the U.S., including the Asian giant hornet (AGH, V. mandarinia). 

      North American Hornet Screening Tool includes fact sheets and an interactive image gallery to support screening for Asian giant hornet and other potentially invasive hornet (Vespa) species. The interactive gallery can be used as a rudimentary key: by choosing one or more of the filters at the top, you can easily narrow down the images to only those that may match your specimen. A more in-depth version of this tool providing specialized information for identifiers on all exotic hornet (Vespa) species, will be released in 2022.

  • Northern Giant Hornet Public Dashboard

    • Washington State Department of Agriculture.

    • The Northern Giant Hornet Public Dashboard shares detection and trapping data. Citizen scientists were able to view detections in real time, including the number of reported sightings and number of hornets confirmed by type. Coordinating this information provided input on future trapping and demonstrated the benefit of collaboration with citizen scientists. WSDA has indicated that citizen data sharing and bottle trapping efforts are crucial to protect Washington from this invasive species.

  • Pest Alert: Asian Giant Hornet

    • Dec 19, 2019

    • Washington State Department of Agriculture.

    • Asian giant hornet is the world's largest species of hornet. In December 2019, WSDA received and verified four reports of Asian giant hornet near Blaine and Bellingham. These are the first-ever sighting in the U.S. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019. If it becomes established, this hornet will have serious negative impacts on the environment, economy, and public health of Washington State. If you think you may have spotted an Asian giant hornet, report it to WSDA's Pest Program and, if possible, include a photo.

  • Proposed Common Name Change for Asian Giant Hornet and Other Hornets

    • Entomological Society of America.

    • The Entomological Society of America (ESA) is accepting comments until June 10, 2022 on a proposed common name for Vespa mandarinia and two related species of Vespa hornets.  Although Vespa mandarinia has been detected in the Pacific Northwest, the other two hornets are not known to occur in the United States.  Currently, Vespa mandarinia is being called many different names in the popular press, but no ESA authorized common name has been established. See Common Names section for more information as it becomes available.
