A new invasive species has been sighted in Old Orchard Beach in several places.
According to the Old Orchard Beach Conservation Commission, Hemlock Woolly Adelgid is an introduced, aphid-like insect from Asia that feeds on hemlocks. HWA affects all species of hemlocks, but does not affect pine, spruce, fir or other conifers.
As of 2011, 18 states from Maine to Georgia have HWA, according to the Maine Forest Service. Many areas infested with HWA display tree decline and mortality.
According to Maine Forest Service experts, HWA eggs and crawlers are present in spring and summer. HWA are easily spread by birds, and residents are urged to avoid hanging bird feeders near hemlock trees, especially from April through August.
Conservation officials warn residents to avoid contact with uninfested hemlocks until the hitchhikers are removed.
Anyone who sees HWA in other areas is asked to call the Maine Forest Service at 207-287-2431.
