The delta flower scarab is also commonly known as the "D beetle." The triangle on the beetle's pronotum has been suggested as mimicry of  the markings on paper wasps in the genus Polistes. The species is diurnal, that is, it is active during daylight. Most of its activities revolve around flowers - they eat pollen and mate almost exclusively on flower blossoms.

Delta flower beetles are members of the subfamily Cetoniinae, commonly called fruit or flower chafers. There are around 4,000 species, many of them still undescribed. Masked Chafer beetle larva take the form of white grubs which live underground and do serious damage to plants, especially turf grasses, by feeding on their roots. As the grubs mature during the late summer and fall, turf damage becomes apparent as brown patches. If the infestation is severe, the grass may be pulled back like a rug, the roots being completely destroyed. Various animal predators such as crows, skunks and raccoons may further damage the lawn by digging for the grubs, a favored food. Grubs may be controlled by spike aeration if they are caught feeding close to the surface, about 45 days after the adult beetles first appear. [1]

Adult delta flower scarabs can be separated from other species by the combination of the following characteristics: epipleuron easily recognizable, border lateral of elytra sinuate and antennal insertion visible from above. Six tribes are normally recognized: Stenotarsiini, Schizorhinini, Gymnetini, Goliathini, Cetoniini, and Cremastocheilini, the last four being found in the New World. The tribe Gymnetini is the biggest of the American tribes, and Goliathini is only found in southern North America. [3]
