The Clemson Home & Garden Information Center has a wealth of pest resources for gardeners and farmers alike. The Muhly Grass Mealybug fact sheet page has a link to an online survey you can use in conjunction with your GPS-enabled smart device to submit photos and report occurrences of the Muhly Grass Mealybug (Stemmatomerinx acircula). This location data from citizen scientists has allowed me to construct a map of Muhly Grass Mealybug distribution throughout the southeastern USA using ArcGIS Online. An interactive online version of that map is embedded below.
