Camponotus semitestaceus

Nests are found under stones or in the soil, surrounded by a small mound (few cms up to 30 cms in diameter). The colonies are large with many majors. Workers are active during the night or during cooler times of the day, and tend Homoptera. Nest density can be very high. (Mackay and Mackay 2002)
