Acmaeodera riograndei
Acmaeodera riograndei is a rarely collected species of metallic wood-boring beetle in the family Buprestidae. First described by Nelson in 1980, this species was historically known only from the Big Bend region of Texas. In May 2022, it was documented from Val Verde County, Texas, representing a significant range extension. Adults have been observed feeding on flowers of Echinocereus enneacanthus carnosus (strawberry cactus) in dry, rocky canyon habitats. The species appears to be active during late spring and early summer, with adults flying to cactus flowers during hot daytime conditions.

Chilocorus cacti
cactus lady beetle, twice-stabbed cactus lady beetle
Chilocorus cacti is a small predatory lady beetle in the family Coccinellidae, native to the New World and introduced to several regions including South Africa, India, and New Zealand. Both adults and larvae are specialized predators of scale insects, with documented consumption of numerous agricultural pest species. The species has been evaluated for biological control programs with variable success. Its common name derives from its frequent association with prickly pear cacti and the distinctive two reddish-brown spots on its otherwise black elytra.

Chloroplus cactocaetes
Texas Cholla Grasshopper
Chloroplus cactocaetes is a spur-throated grasshopper and the sole species in the genus Chloroplus. It is endemic to Texas and closely associated with cholla cacti (Cylindropuntia species). The species was described by Hebard in 1918 and remains poorly known despite its distinctive habitat specialization.

Copestylum
Bromeliad Flies
Copestylum is one of the largest genera of hoverflies (Syrphidae) in the Americas, comprising more than 300 species. The genus is neotropical in origin, with only four species recorded outside the Americas, likely introduced through cactus trade. Larvae are saprophagous and develop in decaying tissues of columnar cacti and other succulent plants, playing important roles in nutrient recycling in xeric environments. Adults are commonly known as bromeliad flies.

Copestylum lentum
Copestylum lentum is a species of syrphid fly in the family Syrphidae. Adults have been recorded from California, Colorado, New Mexico, Arizona, Texas, and Mexico. Larvae are saprophytic, developing in decaying platyclades of Opuntia cacti. The species has been reared from larvae collected in Veracruz, Mexico, and its immature stages and feeding behavior have been described in relation to cephalopharyngeal skeleton morphology.

Copestylum mexicanum, commonly known as the Mexican cactus fly, is a species of syrphid fly in the family Syrphidae. The species is documented in the southwestern United States, with observations spanning multiple states including Oklahoma, Colorado, Utah, Arizona, and New Mexico. Adults have been observed visiting flowers, particularly those of pricklypear cacti (Opuntia species) and other desert flora. The species is part of a diverse assemblage of flower-visiting insects in arid and semi-arid habitats.

Diguetidae
coneweb spiders, desertshrub spiders
The Diguetidae are a small family of haplogyne spiders commonly known as coneweb or desertshrub spiders. They are endemic to the New World and primarily associated with arid and desert environments. Members construct distinctive webs featuring a horizontal sheet with a central tubular retreat, often camouflaged with plant debris. The family contains only two genera and approximately 15 species, with the genus Diguetia being the sole representative in North America. These spiders are considered relatively primitive among araneomorphs due to their unmodified female genitalia and simple male pedipalps.

Moneilemini is a tribe of longhorn beetles (Cerambycidae) containing the genus Moneilema, commonly known as cactus longhorn beetles. These are large, flightless beetles native to North American deserts. The tribe is characterized by fused forewings that form a hardened protective shell, an adaptation correlated with their flightless condition. The group comprises approximately twenty species distributed across western United States and northern Mexico.

Narnia
Narnia is a genus of leaf-footed bugs in the family Coreidae, containing approximately seven described species. The genus was established by Carl Stål in 1862. Species in this genus are found in southwestern North America and Mexico, where they are associated with cacti and other desert vegetation. The genus name predates and is unrelated to C.S. Lewis's fictional world.
