Adults of the Black Vine Weevil hide during the day, and feed at night on the outer edges of leaves, causing a characteristic rounded notch, and the species has a very large host range (100+ kinds of plants), including some trees, fireweed, labrador tea, sheep sorrel, running brambles (<em>Rubus<\/em> sp.), rhododendrons, strawberries, blueberries, cranberries, and many kinds of woody garden plants and flowers. The adult weevil is dull black in color and is unable to fly (its wing covers are fused together). There is only one generation per year.<\/p>\n<p>Other similar broad-nosed weevils in the <em>Otiorhynchus<\/em> genus include the <strong>Raspberry Weevil<\/strong> (<em>Otiorhynchus singularis<\/em>) and one without a common name: <em>Otiorhynchus raucus.\u00a0 <\/em>Besides raspberry, the Raspberry Weevil&#8211;which is also known as the Clay-colored Weevil&#8211;is a major pest of other small fruits as well as numerous ornamental plants (including rhododendron) and conifer seedlings. There is only one generation per year.\u00a0 The adults start to emerge in the spring (March\/April), feed primarily at night, and are most active in the spring and fall. <em><br \/>\n<\/em><\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-1 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 16%;\n\t\t\t}\n\t\t\t#gallery-1 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-1' class='gallery galleryid-2638 gallery-columns-6 gallery-size-thumbnail'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2010\/10\/BlackVineWeevil.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2010\/10\/BlackVineWeevil-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"Black Vine Weevil adult\" aria-describedby=\"gallery-1-467\" srcset=\"https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2010\/10\/BlackVineWeevil-150x150.jpg 150w, https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2010\/10\/BlackVineWeevil-32x32.jpg 32w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a>\n\t\t\t<\/dt>\n\t\t\t\t<dd class='wp-caption-text gallery-caption' id='gallery-1-467'>\n\t\t\t\tBlack Vine Weevil (<i>Otiorhynchus sulcatus<\/i>) (strawberry, raspberry and cranberry pest; rhododendrons are also a host)\n\t\t\t\t<\/dd><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2021\/05\/Raspberry-Weevil-051621.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/extension.umaine.edu\/home-and-garden-ipm\/wp-content\/uploads\/sites\/43\/2021\/05\/Raspberry-Weevil-051621-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"a broad-nosed weevil called a Raspberry Weevil -
