Pogonomyrmex barbatus
red harvester ant, red ant
Pogonomyrmex barbatus is a large harvester ant native to the southwestern United States and northern Mexico. Colonies construct underground nests up to 2.5 meters deep in exposed areas, often marked by conspicuous cleared nest disks. Workers forage primarily for seeds, with foraging activity regulated through olfactory interactions involving brief antennal contacts that assess cuticular hydrocarbon profiles and seed odors. The species exhibits notable physiological variation among colonies in desiccation tolerance and foraging behavior, with some colonies reducing foraging in dry conditions while others maintain activity.
Pogonomyrmex californicus
California harvester ant
Pogonomyrmex californicus is a seed-harvesting ant native to southwestern North America. It is the most widely distributed species in the genus Pogonomyrmex. The species exhibits a striking social polymorphism: most populations have single-queen colonies (monogyny), but some California populations show primary polygyny where multiple unrelated queens cooperate in colony founding and coexist in mature colonies. It possesses a powerful sting and has been used historically by Indigenous peoples for ritual and medicinal purposes. The species is a prominent model for studying the evolution of social behavior, cooperation, and epigenetic regulation of aggression.
Pogonomyrmex californicus subnitidus
Pogonomyrmex californicus subnitidus is a subspecies of the California harvester ant, a seed-collecting ant native to arid regions of western North America. Like other harvester ants, it constructs conspicuous nest disks cleared of vegetation and plays significant ecological roles as a seed predator, soil engineer, and food source for vertebrate predators. The species possesses a powerful sting used defensively against mammalian threats. This subspecies is part of a taxon increasingly recognized as a keystone species in desert ecosystems rather than an agricultural pest.
Pogonomyrmex occidentalis
western harvester ant
Pogonomyrmex occidentalis, the western harvester ant, is a seed-collecting ant native to arid regions of the American West. Colonies construct conspicuous gravel mounds up to 89 cm in diameter, surrounded by vegetation-free nest disks that serve as "islands of fertility" where plants thrive along nest rims. The species possesses a painful, venomous sting used defensively, and plays documented roles as a keystone species in desert ecosystems through soil modification, seed dispersal, and as prey for specialized predators.
Rothschildia
Rothschildia is a genus of giant silkmoths in the family Saturniidae, first described by Augustus Radcliffe Grote in 1896. The genus contains approximately 30 described species distributed from the southern United States through Mexico and Central America to Argentina. Adults are characterized by large size, reduced or vestigial mouthparts, and often striking wing patterns including transparent "windows" devoid of scales. Several species have documented cultural significance for indigenous peoples, particularly the use of cocoons in ceremonial regalia.
Rothschildia lebeau
Lebeau's Silk Moth, Forbes Moth
Rothschildia lebeau is a giant silkmoth in the family Saturniidae, distributed from the Lower Rio Grande Valley through eastern Mexico to Brazil. Adults are short-lived and do not feed, relying on fat reserves accumulated during larval development. The species exhibits a life history tradeoff between larval survival and adult body size based on host plant quality, with larger males showing higher mating success.
