The life cycle of the glassy-winged sharpshooter begins when the overwintering adults lay their first brood in Spring <sup>1<\/sup>. Nymphs, which are approximately 2mm long, hatch fourteen days later. The GWSS has five instars (developmental stages) before reaching adulthood <sup>1<\/sup>. The second brood hatches between June and October which become the overwintering adults <sup>1<\/sup>. The adult glassy-winged sharpshooter is 13mm long with dark brown coloration, clear wings with red veins, and a yellow or white abdomen <sup>1<\/sup>. The nymphs appear similar to adults, only smaller (9mm) and without wings <sup>1<\/sup>. They feed on the sap of non-deceduous plants and deciduous plants in late winter <sup>1<\/sup>. Nymphs feed on non-lignified petioles and stems <sup>1<\/sup>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"483\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4-1024x483.jpg\" alt=\"\" class=\"wp-image-45\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4-1024x483.jpg 1024w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4-300x141.jpg 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4-768x362.jpg 768w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4-1536x724.jpg 1536w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/7073\/files\/2023\/08\/4.jpg 1880w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Due to the large number of possible host plants, over 200, the glassy-winged sharpshooter is found in residential landscaping, agricultural fields, and wild lands <sup>2<\/sup>. The GWSS is known to feed on at least 70 species of plants <sup>2<\/sup>. A native to the southeastern United States and northeastern Mexico, the glassy-winged sharpshooter spreads easier than other leafhoppers due to its ability to fly between 3 to 16 feet per jump enabling it to travel a quarter mile per day <sup>2<\/sup>. The glassy-winged sharpshooter is of economic concern due the xylem penetrating mouthparts that carry and move plant pathogenic bacteria from one plant to another <sup>2<\/sup>. The GWSS is the primary vector of concern for Pierce&#8217;s disease which is spread from plant to plant as insects feed on individuals infected with the bacteria <em>Xyllela fastidiosa <\/em><sup><em>1<\/em><\/sup><em>.<\/em><\/p>\n\n\n\n<p><strong>References<\/strong><\/p>\n\n\n\n<p>1.
