Since Asian giant hornets were spotted late last year in British Columbia and in the Blaine area, the Washington State Department of Agriculture has developed a system for reporting sightings.
As shown on the above WSDA map, there have been dozens of sightings reported to WSDA to date with 3 confirmed, including 1 this year.
Many sightings are accompanied with photos and descriptions of observed behavior. From those observations and photos, WSDA entomologists have been able to determine many sightings were of other species. Often reports are of native wasps which they point out can look very similar to the Asian giant hornet.
