Winged female thief ant
Columbia Ca 6-22-21
Winged female thief ant. 3/8 inches long.
Dr. Philip Ward confirmed the ID. He pointed out that the taxonomy of thief ants (Solenopsis species in the erstwhile subgenus Diplorhoptrum) is in a rather unsatisfactory state. This queen could be called Solenopsis molesta, the most common North American species, but the boundaries of that species remain unclear.
