Natural History:

This rarely-collected species occurs in the high canopy of lowland rainforest trees. Some collections have come from insecticidal fogging of the canopy (Luehea seemannii in Panama, the Erwin fogging program in Peru). Weber (1938) obtained the winged queen of P. guianensis from the stomach of Bufo marinus. An LACM specimen is a queen head capsule collected from the feces of a silky anteater (Cyclopes). The only known nest collection was by W. L. Brown, Jr., from near Manaus. The collection contains a dealate queen and a male.
