Cacama crepitans
Coastal Cactus Dodger
A medium to large cicada species commonly known as the Coastal Cactus Dodger. Males produce a loud, distinctive song described as a high-pitched metallic buzz or shrill, often delivered in short bursts. The species is closely associated with cactus hosts, particularly cholla and prickly pear, in arid and semi-arid regions. Adults are fast-flying and alert, making them challenging to approach. Females oviposit into dry, dead cactus stems rather than living tissue.

Cactobrosis fernaldialis
blue cactus borer
Cactobrosis fernaldialis, commonly known as the blue cactus borer, is a snout moth species found in desert regions of the southwestern United States. Adults exhibit bivoltine flight periods in spring and late summer through autumn. The species is notable for its larval specialization on Ferocactus wislizeni.

Chelinidea vittiger
cactus coreid, cactus bug, squash bug
Chelinidea vittiger is a leaf-footed bug in the family Coreidae that feeds and develops almost exclusively on prickly pear cacti (Opuntia spp.). It has been studied for its potential use in biological weed control, particularly for managing invasive Opuntia species. The species occurs across North America, Central America, and Australia, with its distribution closely tied to that of its host plants. It can be considered either beneficial or pestiferous depending on context: it helps prevent prickly pear from aggressively overtaking rangelands, yet may also damage cacti used as emergency forage or produce.

Chelinidea vittiger aequoris
cactus bug, cactus leaffooted bug
Chelinidea vittiger aequoris is a subspecies of cactus bug in the leaf-footed bug family Coreidae. It is a specialist herbivore that feeds almost exclusively on prickly pear cacti (Opuntia spp.), with its range closely tied to the distribution of these host plants. The species is found across the United States and southward into northern Mexico, with the subspecies aequoris occurring in specific regions. In Missouri, it occurs on Opuntia humifusa in sand prairies and glades, and on O. cespitosa in igneous glade habitats.

Diadasia australis
Cactus chimney bees
Diadasia australis is a species of chimney bee in the family Apidae, found in Central America and North America. The species belongs to a genus commonly known as chimney bees or turret bees, characterized by their distinctive nest architecture. Three subspecies are recognized: D. a. australis, D. a. californica, and D. a. knabiana. The species is part of a group of solitary bees that construct above-ground turret structures at their nest entrances.

Diadasia rinconis
Cactus Bee
Diadasia rinconis is a solitary ground-nesting bee in the family Apidae, commonly known as the cactus bee. In the Sonoran Desert, it feeds almost exclusively on native cactus species, with its life cycle closely tied to cactus flowering phenology. Males form large mating aggregations where hundreds or thousands patrol nesting areas and compete in "mating balls" for access to emerging females. The species exhibits pronounced sexual dimorphism, with females possessing specialized pollen-collecting structures and males showing elongated hind legs.

Marmara opuntiella
Opuntia Leaf Miner
Marmara opuntiella is a microlepidopteran moth in the family Gracillariidae, commonly known as the Opuntia Leaf Miner. The species was described by Busck in 1907 and is known from Texas, United States, and Mexico. Larvae create distinctive mines in the leaves of cactus hosts. Records of similar larvae with identical habits from Colombia, Cuba, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Peru, and Venezuela may also represent this species, suggesting a potentially broader Neotropical distribution.

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 armatum
Black Cactus Longhorn Beetle, Armed Cactus Longhorn Beetle
Moneilema armatum is a flightless, jet-black longhorn beetle endemic to North American desert regions. Adults are large, bulky, and slow-moving, with reduced wings and a distinctive habit of raising their abdomen when disturbed—a defensive posture convergent with darkling beetles. The species feeds exclusively on cacti in the genus Opuntia and related opuntioids, with larvae boring into stems and roots while adults feed externally on pads and stems. Population genetic studies reveal pronounced geographic structure, with northern and southern clades separated near the Arizona-Sonora border, indicating long-term isolation in Pleistocene refugia followed by post-glacial range expansion.

Moneilema gigas
Giant Cactus Longhorn Beetle, Cactus Longhorn Beetle
Moneilema gigas is a large, flightless longhorn beetle endemic to the Sonoran Desert. Adults and larvae feed on cacti, particularly chollas, prickly pear, and saguaro seedlings. The species exhibits Mullerian mimicry of noxious stink beetles (Eleodes). Phylogeographic studies indicate northward range expansions following Pleistocene climate changes, with populations expanding from multiple glacial refugia.

Narnia femorata
Leaf-footed Cactus Bug
Narnia femorata is a leaf-footed bug (Coreidae) native to the southern United States and Central America. The species was introduced to Florida in the 1960s via nursery stock and is now fully established. It feeds primarily on cactus fruit, especially Opuntia species, using a long tube-like beak. Males possess enlarged, spiny hind femora used as weapons in male-male combat for territories on cactus pads bearing fruit. The species exhibits pronounced phenotypic plasticity, with body size, weapon size, and beak length changing seasonally in response to host plant fruit availability. Populations have been documented utilizing Cirsium thistle as an alternative host, representing a recent host range expansion.

Pseudoschinia
Pseudoschinia is a monotypic genus of crambid moths established by Munroe in 1961. The sole species, Pseudoschinia elautalis, is a specialist herbivore of cacti in the southwestern United States and northern Mexico. Adults are small moths with distinctive pale yellow forewings and white hindwings. The genus is notable for its narrow ecological association with columnar and cholla cacti.
