Listronotus maculicollis

The annual bluegrass weevil, scientific name Listronotus maculicollis, is a turfgrass insect pest which feeds mainly on annual bluegrass (Poa annua). They prefer to feed on very low mown grass, and are thus found mostly on golf courses or grass tennis courts. 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).
