Twolined Chestnut Borer

Abstract

The twolined chestnut borer, Agrilus bilineatus (Weber), belongs to the beetle family Buprestidae. The word chestnut refers to the beetle's past status as a principal pest of American chestnut, Castanea dentata. The twolined chestnut borer is found from the Maritime Provinces of Canada, west to the Rocky Mountains, and south to Florida and Texas.
