Midlawn and Cardinal were so-so. Those that were either dead or close to it included Mini-Verde, Shanghai, Tift 94, Tifway and Tifgreen. Midfield, Midiron and Quickstand were not included in the study but have shown cold hardiness in other trials. There have been numerous reports of sod webworm moths flying over lawns recently. At rest, they clasp or roll their wings close to their bodies.
Mouthparts project forward from the head like a snout.
The moths are usually noticed when flushed out by people walking. They fly in a jerky zig-zag manner and quickly return to the grass to hide. Around dusk, they may be seen flying a few feet above the grass and dropping their eggs. In a few days, these eggs and others laid on the lower parts of grass stems hatch into small caterpillars. It is these caterpillars that damage the grass.
