Dark-Winged Fungus Gnats
These dark-winged fungus gnats were collected by Ryles Richards, 10 November 2016, in Coulterville.
They are small, about 2 millimeters long.
The wing venation shows a shifting, down and back, compared to the typical wing venation shown for Sciara sp.
Dark-winged fungus gnat infestations in homes are likely coming from house plants.
