Explanation of Names
Clogmia albipunctata (Williston 1893)
albipunctata = 'white-dotted'
"The best and easiest way to distinguish C. albipunctata from any other species in our area are the two spots in the middle of each wing." Zachary Dankowicz comment on iNat

White antennae and white spots on edges of wings and tips of leg segments(1)
Originally mostly tropical, now found in human habitats across North America
Typically water with decaying organic matter -- tree holes, stagnant ponds, drains, in containers or trash filled with water, bathrooms, kitchens, in sewers, and near wastewater treatment plants
