This is a visually striking beetle belonging to the longhorn family Cerambycidae, characterized by a robust and elongated body that ranges from 20 to 35 millimeters in length. Its base coloration is predominantly glossy black or deep dark brown, beautifully contrasted by vibrant yellow or bright orange transverse bands across the elytra, a pattern that displays slight individual variation. The pronotum is rough and broadened laterally, bearing small distinct tubercles, often featuring dark reddish or orange patches on its disc, which gives rise to its specific epithet. The antennae are remarkably long, significantly exceeding the body length in males, and present alternating dark and pale segments that serve as an excellent diagnostic feature in the field. Its limbs are strong, adapted for grasping tightly to tree bark, and terminate in tarsi equipped with effective adhesive pads.

Geographical distribution: This species is widely distributed throughout the temperate and subtropical regions of South America. Its native range encompasses much of central and southern Brazil, extending into eastern Bolivia, the entirety of Paraguay, northern and central Argentina (reaching down to the Pampean provinces), and mainland Uruguay. It easily disperses through forested biological corridors as well as rural and suburban areas with suitable tree cover.

Habitat: It primarily inhabits open woodland biomes, transition zones like the wet and dry Chaco, the Espinal ecoregion, and gallery forests. However, it exhibits remarkable ecological plasticity, successfully adapting to commercial fruit orchards, exotic forestry plantations, urban parks, and domestic gardens containing viable host trees, showing high tolerance to habitat fragmentation.

Feeding: During their adult stage, these beetles are primarily phytophagous and glycivorous, actively feeding on sugary sap exuded from tree trunk wounds, ripe or decaying fruits (particularly figs and citrus), and occasionally pollen and nectar from various wild flowers. In contrast, the larvae are strictly xylophagous, boring into and consuming the inner wood of trees belonging to the Moraceae, Fabaceae, and Salicaceae families, showing a pronounced preference for the common fig tree (Ficus carica), willows (Salix spp.), and the chinaberry tree (Melia azedarach).

Behavior: It exhibits mainly diurnal and heliophilic habits, remaining highly active during the hours of peak sunlight during the warm spring and summer months. Adults are strong, loud flyers that move actively through the tree canopy in search of food or potential mates. When threatened or handled, they can produce an audible squeaking sound through a stridulation mechanism by rubbing the prothorax against the mesothorax, a defense behavior meant to deter predators like birds and larger predatory insects.

Reproduction: The reproductive cycle begins in late spring with courtship rituals taking place directly on the trunks of host trees. Following copulation, the female uses her ovipositor to deposit eggs individually or in small clusters deep within bark crevices or damaged areas of weakened branches. Upon hatching, the larvae penetrate the bark and begin excavating deep, winding galleries in the heartwood, consuming cellulose for a period that typically lasts one to two years. Once larval development is complete, they construct a pupal chamber near the bark surface, where they undergo metamorphosis to emerge as adults at the beginning of the next warm season.

Conservation status: This species is currently not evaluated (NE) by the International Union for Conservation of Nature (IUCN) and is not listed under any national red lists. Due to its extensive geographical distribution, high adaptability to human-altered landscapes, and abundance in agricultural zones where it is occasionally viewed as a minor orchard pest, its populations remain stable and face no immediate threats of extinction.
