Description:<\/strong>\u00a0<\/strong>Adult moths are brown moths with wing spans of about 3\/4 inch. Wings are held flat over the back when at rest, giving the insect a triangular appearance. Caterpillars grow to almost 3\/4 inch long, appearing translucent green with small dark-colored spots or plates arranged on each body segment and a dark, yellowish-brown head capsule. Several other species of\u00a0sod webworms\u00a0occur in Metaire Louisiana, mainly from the genus,\u00a0Crambus<\/em>. These sod webworms can be distinguished in the adult stage by the way the moths roll their wings around their bodies when at rest rather than holding them out. Larvae are distinguished by the different patterns of plates (panicula) on their thoracic segments. Other common plant-feeding pyralid moths include the\u00a0genista caterpillar,\u00a0Uresiphita<\/em>\u00a0reversalis<\/em>\u00a0(Guenee) (See also the\u00a0fall webworm) and the\u00a0lesser canna leafroller,\u00a0Geshna<\/em>\u00a0cannalis<\/em>\u00a0(Quaintanaca)<\/p>\n \u00a0<\/strong><\/p>\n Life Cycle:<\/strong> In Louisiana\u00a0females lay creamy white eggs in clusters of up to 15 eggs on grass blades, stems and turf debris. Tiny 1\/32 inch long caterpillars hatch from eggs in 6 to 10 days and develop through 7 or 8 stages (instars) over 25 to 50 days, depending upon temperature April – September. Larvae form a 3\/8 inch long reddish-brown pupa in the thatch, sometimes within a shapeless bag spun by the caterpillar. Development from egg to adult occurs in about 6 weeks. Several generations occur during the year, but those occurring in the fall are larger, overlapping and potentially more damaging to turfgrass causing large areas to be damaged in a week or two. This species only survives in areas with mild winters that allow all stages to continue to develop.<\/p>\n \u00a0<\/strong><\/p>\n <\/p>\n Caterpillars feed during the night on turfgrasses, including Bermudagrass, St. Augustinegrass, centipedegrass, Bahiagrass, and zoysiagrass.<\/p>\n Injured grass blades initially appear notched and ragged as tissues are removed from the edges until the entire leaf is consumed. Injured turf is usually spotty within a lawn, but damaged areas enlarge as caterpillars migrate in search of more food. Heavily injured turfgrass may die but usually recovers. St. Augustine grass recovers more slowly than bermudagrass. Caterpillars can be forced up out of infested turfgrass by sprinkling a solution of liquid dishwashing detergent in water on the turf. Caterpillars will climb up on grass blades.<\/p>\n \u00a0<\/strong><\/p>\n \u00a0<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Description:\u00a0Adult moths are brown moths with wing spans of about 3\/4 inch.
