San Antonio Carpenter Ant
CARPENTER ANTS
Fourteen species of carpenter ants are indigenous to the Lone Star State. The largest is the black carpenter ant (shown), and is found primarily in wooded areas outdoors. The common indoor species have workers that are dull red bodied with black abdomens. Worker ants range in size from 1/4 to 1/2-inch. They can be distinguished from most other large ant species because the top of the thorax is evenly convex and bears no spines. Also the attachment between the thorax and abdomen (pedicel) has but a single flattened segment.
