Comments: The Neponset River Watershed Association introduced these European beetles in Fowl Meadow in Canton and Norwood to control invasive purple loosestrife. They have spread to Sharon, where they are having the desired effect of keeping the invasive purlple loosestrife in check so native plants can thrive.
