 ABWs, as they are often referred to, were only found in the Northeastern United States until the 2000s when sightings began to expand.In recent years they have been found as far north as Ontario and Quebec, as far west as Ohio, and as far south as North Carolina.Their choice of hosts has also expanded, and they have been reported feeding on perennial ryegrass ("lolium perenne") and creeping bentgrass ("Agrostis stolonifera").
