Natural History:

This species prefers dry forest or scrubby habitats. It nests in live or dead stems. I have the following nest collections:

Nest in dead stick.

A sprawling vine had soft pith and was commonly inhabited by ants. A series of nest collections made, all from live stems.

Small treefall that had been down long enough for leaves to be dry and brown. Nest in hard dead wood.
