Possible Formica aerata in Groveland California, Tuolumne County

Ryles Richards brought in samples of an unusual ant he saw at a home in Pine Mountain Lake, Groveland, California. He said the ants were very fast and ran in erratic paths, not following trails. We took photos and sent them to Dr. Philip Ward for ID. Based on these photos, he thinks they might be Formica aerata.
