The arboreal traps were designed to catch insects moving on tree trunks. His specimens were killed and then preserved for an indeterminate amount of time in an aqueous solution of picric acid. Since the seasonal flooding permits only a scant layer of leaf litter to accumulate at the end of the dry season, it is assumed this species is more likely an arboreal rather than a leaf-litter or subterranean ant, despite having very small arolia.</paragraph>

Due to its proximity to Manaus, the area where this specimen was found is frequently used for research purposes by academic programs, such as those of INPA. The voucher specimens collected by Adis are deposited in the INPA collection. One of us searched for additional specimens there, but none could be found, suggesting it is a relatively rare species or has a biology that keeps it from being frequently collected by the usual field techniques. The large eyes could imply activity in low-light conditions, such as during the night, but also this is a functional trait linked to flight, for example, during mating and nest search (
