Representing a visually striking lineage within the leaf beetle family Chrysomelidae, this species is characterized by its oval, dorsoventrally flattened body shape, which closely resembles a miniature tortoise shell. It features specialized transparent or semi-opaque lateral expansions of the pronotum and elytra that cover and protect the head and appendages when the insect clings to a leaf surface. The dorsal coloration is highly diagnostic, featuring a reflective base of metallic deep blue or iridescent green, contrasted by symmetrical markings of vibrant crimson red or bright orange situated across the elytral disc. Adults measure between 11 and 15 millimeters in length. The pronotal surface is relatively smooth, while the elytra exhibit irregular punctation and faint longitudinal ridges visible under close inspection.

Geographical distribution: This insect is native to the Neotropical region of South America, with established populations primarily documented in Brazil (ranging from Rio de Janeiro down to Rio Grande do Sul), Paraguay, Uruguay, and northeastern Argentina (including the provinces of Misiones and Corrientes). Its distribution closely mirrors the presence of native riverine forests and semi-deciduous woodland systems in these regions.

Habitat: It is mostly found in the undergrowth and shrub layers of humid biomes, such as the Atlantic Forest, gallery forests, edge habitats of secondary forests, and transition zones bordering the Cerrado. It thrives in microhabitats with high relative humidity and moderate sunlight penetration, where its specific host plants grow abundantly.

Feeding: It is an obligate phytophagous insect during both larval and adult stages, specializing on host plants within the Convolvulaceae family, particularly species of the genera Ipomoea and Merremia. Both larvae and adults consume leaf tissue, creating irregular skeletonized patterns on the foliage of their host vines.

Behavior: It exhibits diurnal activity, with peak locomotion and feeding occurring during the warmest hours of the day when it performs short, clumsy flights between host plants. When threatened, it withdraws its antennae and legs underneath its expanded elytral margins and presses its body flat against the leaf surface, securing a tight grip using specialized adhesive tarsal setae. If further provoked, it will release its grip and drop into the leaf litter below, practicing thanatosis (feigning death). Larvae possess a unique defensive strategy, constructing a defensive shield composed of accumulated feces and cast larval skins (exuviae) held over their bodies by a specialized anal fork, which serves as an effective physical and chemical deterrent against predators like ants.

Reproduction: The life cycle begins with a simple courtship ritual driven by short-range pheromones emitted by the female. Copulation takes place directly on the host plant leaves. Following fertilization, the female deposits small clusters of eggs protected by a papery, protective ootheca-like structure on the underside of the leaves, shielding them from environmental desiccation and parasitoid wasps. The larvae hatch after several days and progress through five larval instars, feeding gregariously during the early stages before becoming more solitary. Pupation occurs directly on the leaf surfaces, where the pupa anchors itself by its posterior end using the remains of the final larval skin.

Conservation status: It has not yet been formally assessed by the International Union for Conservation of Nature (IUCN), meaning it does not hold an official conservation category. However, local populations face silent declines due to the ongoing fragmentation of the Atlantic Forest, agricultural expansion, and the heavy use of chemical insecticides in surrounding rural areas.
