California Harvester Ants

We suspect none of our readers will be as excited about this posting as we are, but we are happy to report that the colony of California Harvester Ants that has been living on a south facing slope in Mount Washington is still present, though perhaps not for long as every available lot in the neighborhood seems to have a “Notice of Intent” sign for a new construction project.  California Harvester Ants are naturally adapted to our Southern California climate and they do not need irrigation to survive, but alas, garden landscaping is responsible for the spread of that scourge, the Argentine Ant, and they have displaced our native Ant species in much of urban Los Angeles.

We also located what we believe to be the back door to the colony right at the edge of the street.
