Natural History:

This tiny species inhabits highly insolated habitats. In Costa Rica I know it mainly from Corcovado National Park, where it seemed to be more common near the beach margin than further inland. I collected it five times in Corcovado, and all the collections were from the beach edge. Four of the collections were diurnal foragers (one on a Cissus inflorescence, one on a Simaba cedron inflorescence, others on low vegetation). One collection was a nest in the hollow stem of a small Salvia-like plant on one of the rock islands at Llorona. At Carara, near the headquarters building, I found a nest in a 7mm diameter dead stick in roadside vegetation.
