Subject: What the hell are these
June 21, 2014 8:53 am
Yesterday morning I came across 5 groups of these slugs (I believe that’s what they are). I live in North West Arkansas. So far I haven’t been able to find anything on web about what these little guys actually are. Most people are telling me that they are tent caterpillars, but I don’t believe that is correct.

Dear J Ramey,
This is a crawling mass of Fungus Gnat Larvae in the family Sciaridae. According to the Home, Yard & Garden Newsletter at the University of Illinois: “Fungus gnat larvae are more likely to be numerous in areas with an overabundance of water from rainfall or irrigation. Over-watering newly laid sod can result in large populations of these larvae eating young roots. Reducing irrigation will cause a reduction in the number of fungus gnat larvae and allow the sod to root. These larvae are not likely to cause any damage to established turf and can be ignored or washed away with heavy streams of water. As adults, they are known as dark-winged fungus gnats, which are frequently very common in the spring and fall in Illinois, flying as large swarms up to several feet across.”
