Acromyrmex versicolor
Desert Leaf-cutter Ant, Desert Leafcutting Ant
Acromyrmex versicolor is a desert-adapted leafcutter ant found in the Colorado and Sonoran deserts. Colonies exhibit pleometrosis, where multiple queens cooperate to found nests, though typically only one queen survives to establish a mature monogynous colony. Workers collect living and dead leaves to cultivate fungus gardens, the sole food source for the colony. The species is notable for forming large, distinctive nest craters covered with leaf fragments and for its flexible foraging behavior that shifts between diurnal and nocturnal activity depending on temperature.

Crematogaster pilosa
Hairy-headed Acrobat Ant
Crematogaster pilosa is a polydomous ant species native to the southern Atlantic coast of the United States and some interior areas. It forms multiple spatially separated nests per colony, typically inhabiting tidal marshes, wet meadows, and other wetland environments. The species nests in plant stems, logs, and fallen branches. Its common name 'Hairy-headed Acrobat Ant' refers to its pilose (hairy) head and the characteristic acrobat ant behavior of raising the gaster (abdomen) over the thorax when disturbed.

Crematogastrini
Crematogastrini is a tribe of ants within the subfamily Myrmicinae, comprising approximately 64 extant genera and 8 fossil genera. Members of this tribe are distributed globally and exhibit considerable morphological and ecological diversity. The tribe includes the well-known genus Crematogaster, which is among the most species-rich ant genera worldwide. Crematogastrini ants are primarily arboreal or ground-nesting, with many species establishing mutualistic relationships with plants and other insects.

Cyphomyrmex
fungus-growing ants
Cyphomyrmex is a genus of small, drab-colored fungus-growing ants in the tribe Attini, found primarily in the Neotropics. These ants cultivate fungi in the tribe Leucocoprineae as their primary food source, with most species growing fungal nodules rather than full mycelial gardens. Colonies are typically monogynous and small, rarely exceeding 500 workers. The genus is divided into two species complexes: the strigatus complex (South America only) and the rimosus complex (southern North America to South America). Cyphomyrmex represents a basal lineage among attine ants and serves as sister group to Mycetophylax.

Tetramorium immigrans
Immigrant Pavement Ant, Pavement Ant, Sugar Ant
Tetramorium immigrans is a highly successful invasive ant native to Europe that has become one of the most abundant ant species in urban North America. The species thrives in disturbed, paved environments and exhibits remarkable thermal tolerance, with workers surviving temperatures up to 46°C. Colonies are typically large, with thousands to over 10,000 workers, and are highly territorial, engaging in conspicuous inter-colony battles. The species was previously misidentified as Tetramorium caespitum until a 2017 taxonomic revision clarified its status as a distinct species within the T. caespitum complex.

Veromessor
Veromessor Harvester Ants
Veromessor is a genus of North American harvester ants comprising ten species, all endemic to western and central North America. The genus was revived from synonymy with Messor by Ward et al. (2015). These ants exhibit striking ecological and morphological diversity despite the small number of species, including variation in colony size, foraging strategies, mating phenology, and colony founding modes. They serve as important ecological models, with some species studied extensively for their navigation systems and social behavior.

Veromessor andrei
Andre's Harvester Ant
Veromessor andrei is a North American seed-harvester ant endemic to western North America. Formerly classified in the genus Messor, it was reclassified to Veromessor based on phylogenetic studies. The species exhibits color polymorphism, with workers varying in coloration. Like other Veromessor species, it is a granivorous ant that harvests and stores seeds, playing a significant ecological role as a keystone species in arid and semi-arid habitats. The species has been the subject of behavioral and ecological research, though less extensively studied than V. pergandei.
