Camponotus herculeanus (Formicidae)

the carpenter ants



Black or red thin-waisted bodies, 7-15 mm in length. Winged forms possess two pairs of wings which are unequal in size and have reduced venation. Contrast these winged ants with the termites.
Camponotus herculeanus adult ants.  



Wood is extensively excavated to provide nesting sites only, fiber is not used as a food source. Additional damage may occur on root collars of seedlings and saplings. The ants tend aphids and feed on their honeydew excretion.



Principal Hosts:

Wood is excavated to provide nesting sites, not for food.

Stumps, logs, dead standing trees of all species and wooden portions of buildings.










Economic Importance:

In the Pacific Northwest, carpenter ant damage to buildings is more prevalent than that done by termites.
