This species occurs in transitional tropical-temperate cloud forest. One colony collected at Rancho Cielo by P. S. Ward was in a rotten log. Another I found on Mt. Orizaba was under a large rock in hardwood forest dominated by Liquidambar and Carpinus, with a Cyathea-melastome understory. Winged queens were present in a nest at Rancho Cielo on 23 July.
