Imported Red Fire Ant
Solenopsis invicta

In spite of all efforts to prevent them, fire ants have recently arrived in Southern California.

A small colony of fire ants just getting started in the edge of my lawn. There are a few ants in the picture, but they are not easy to see.

Here is a well established colony at the base of a utility pole.

By placing masking tape, sticky side up, next to the ant hill, some of the ants were immobilized for easier examination.

Here is a view through a magnifying glass.
