This is a non-biting midge (Diptera: Chironomidae)l see http://tinyurl.com/mpx96u3 for an image. These are close relatives of mosquitoes, and like them, their larvae are aquatic. Although harmless, these insects can occur in large numbers and make terrible nuisances of themselves. Ed Saugstad, retired entomologist; Sinks Grove, WV.
