Natural History:

This species prefers rainforest habitats. I most often encounter it as workers in recent treefalls or on low vegetation. I have seen two nests, both in dead stems:

Nest in 11mm diameter dead stick in Acacia ruddiae tree.

Nest in a hollow twig, 26cm long, 4mm outside dia., 2mm inside dia. The top had been broken off. Soldiers were on top, nearest the entrance, and a group of three blocked the mouth of the nest and slowly moved backwards as I broke open the nest. Nest contents were 93 minors (including callows), 10 majors, 26 pupae, 10 large larvae, and small brood.
