Cuterebra austeni
Cuterebra austeni is a species of New World skin bot fly in the family Oestridae. The adult flies are large, bumble bee-sized insects with distinctive black and white coloration. Like other Cuterebra species, adults lack functional mouthparts and live only briefly, fueled entirely by larval fat reserves. The species has been documented exhibiting hilltopping behavior in Arizona, where males gather at elevated sites to locate females.
Polistes arizonensis
Arizona Paper Wasp
A social paper wasp found in the southwestern United States and Mexico. Once considered a subspecies of Polistes exclamans, it is now recognized as a distinct species. It builds exposed paper nests under palm fronds, shrubbery, and man-made structures. Females produce ant-repellent secretions from sternal glands to protect nests. The species is notably tolerant of close human observation and can be distinguished from similar Polistes species by facial coloration and geographic range.
Trichoton sordidum
Trichoton sordidum is a small, flightless darkling beetle (Tenebrionidae) native to the Sonoran Desert borderlands of southern Arizona and northern Mexico. The species exhibits sophisticated behavioral thermoregulation, including photonegativity and temperature-dependent activity patterns. Under resource limitation or environmental stress, individuals form adhesive aggregations or physical clumps of 2–10 beetles as a threat evasion mechanism. Dispersal follows cohesive patterns consistent with Minimum Risk Distribution models.
