| Pheidole indagatrix|
According to Longino (1997), indagatrix occurs in moist to wet forests, both on the ground and in the canopy, and forages both day and night. It is equally flexible in nesting sites, with colonies having been found variously in and under dead wood on the ground, and in one case each, under accreted soil on the side of a tree trunk and in a hollow live stem. Winged males have been found in nests in January and March. (Wilson 2003)
