Where do velvety tree ants typically build their colonies?

Velvety tree ants are known for their preference for specific habitats when establishing their colonies. They typically build their colonies in tree hollows, old stumps, and underground. These locations provide the necessary protection, humidity, and resources that these ants require for survival and reproduction. Hollow trees and old stumps offer a safe environment that shields the colony from predators and environmental extremes while facilitating the foraging activities of worker ants.

The other options describe locations that are not characteristic of velvety tree ants' nesting behavior. While some insects might establish themselves in grass or sandy deserts, velvety tree ants favor arboreal and moist environments, making option B the most accurate representation of their typical nesting sites.
