This is a poorly known species. The synonymous form N. peninsulare HNS was described from a few workers taken under a stone. Watkins (1971) also reported finding it under a stone in Texas and “ ... observed a few workers ... in a weak nocturnal raiding column of N. opacithorax HNS ... ” Our specimens from 9 - mile Canyon were found in soft sand at a depth of about 45 cm. This was in Sagebrush Desert with some intermixed Larrea. This ant has also been collected from Creosote Bush ScrubJoshua Tree Woodland. In the chaparral biome of Deep Canyon, Wheeler and Wheeler (1973) found a nest under a slightly buried stone.
