Coenopoeus
Coenopoeus is a genus of longhorn beetles (Cerambycidae) in the subfamily Lamiinae, tribe Acanthocinini. The genus contains two described species: Coenopoeus niger and Coenopoeus palmeri. These beetles are associated with cactus habitats, with C. palmeri specifically documented as feeding on staghorn cacti (Cylindropuntia species). Adults are nocturnal and feed externally on cactus tissues, while larvae are internal miners within cactus stems.

Coenopoeus palmeri
Coenopoeus palmeri is a cactus-associated longhorn beetle (Cerambycidae: Lamiinae) and the sole member of its genus. Described by LeConte in 1873, it is specialized on staghorn cacti (Cylindropuntia spp.), with larvae mining internally within cactus stems and adults feeding externally at night. The species is found in the southwestern United States and northern Mexico, with adults active primarily in spring and summer.

Moneilema annulatum
cactus beetle, ambulated cactus beetle
Moneilema annulatum is a flightless cactus beetle in the family Cerambycidae, first described by Thomas Say in 1824. Adults are found almost exclusively on opuntioid cacti (prickly pears and chollas), where they feed on plant tissues and flowers. Larvae tunnel within cactus stems, often causing visible damage in the form of hardened black exudate. The species occurs across western North America from the Great Plains to the Pacific coast.

Moneilema blapsides
cactus beetle
Moneilema blapsides is a flightless, darkling beetle-mimicking longhorned beetle in the family Cerambycidae. First described by Newman in 1838, it belongs to a genus of cactus beetles found primarily in arid regions of North America. Like other Moneilema species, it exhibits Batesian mimicry of Eleodes darkling beetles, including the characteristic head-standing defensive posture when disturbed.

Plagiostira albonotata
white-marked shieldback
Plagiostira albonotata, commonly known as the white-marked shieldback, is a species of shield-backed katydid in the family Tettigoniidae. It is a large, robust katydid found in arid regions of the southwestern United States. The species is characterized by distinctive white markings on its body. Observations indicate activity during summer months in desert and semi-desert habitats.

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.
