Their host plants include rice, amaranth, thorn wide, lotus seed grass, earth nepeta, straw grapes, corn, soybeans, and more. This wide range of hosts makes them a serious threat to various crops, especially in areas where rice is a major crop.

In terms of damage, nymphs feed by sucking the sap from rice plants or damaging grass berries, which can lead to stunted growth, yellowing leaves, and reduced yields. The adults also contribute to plant damage, further impacting crop health and productivity.

Morphologically, the long-shouldered spiny beak has an adult body length of 7.5–8.8 mm and a width of 4–5 mm. The antennae segments 1–3 are dark brown and equal in length, while segment 4 is dark brown with a red tip. The front half of the prothoracic plate is lighter in color, and the lateral angles extend outward as spines without being upturned. Clear white spots are visible in the inner corners of the black leather flaps. The scutellum is coarse, and the base segments of the fore and midlegs each have two small black spots. The body color is light, with four dark spots on the abdomen and two smaller or less noticeable spots in the middle.

The eggs are rhombic in shape, initially white, then turning yellowish and translucent over time. The last-instar nymphs are tan and brown, with small black lines along the back of the abdomen. The lateral angles of the prothorax extend outward into needle-like structures, and the wing buds reach the posterior edge of the third abdominal segment. The short-shouldered spiny beak is similar in appearance but slightly smaller, with a body length under 9 mm. It has shorter frontal and thoracic spine angles, and the width between the side corners is less than half the body length, making it distinguishable from its long-shouldered counterpart.

In terms of life habits, the species in the Yangtze River Basin typically complete 2–3 generations per year. Adults overwinter in leaf litter or dry grass clumps. They begin laying eggs in March or April of the following year, usually on leaves, ears, or stems of host plants. This reproductive cycle allows for rapid population growth and continued damage to crops throughout the season.

For prevention and control, it's recommended to follow standard practices used for managing rice spiny beaks. These may include cultural controls, such as maintaining clean fields and removing weeds, as well as the use of insecticides when necessary. Monitoring populations early in the season can help prevent large-scale infestations and reduce economic losses.
