The front and sides of the body are wide, like turtles. Both adults and larvae are harmful to horticultural plants. Gem tortoise shell in South America (Desmonota? Variolosa) is densely covered with potholes and ditches, and the flashing green layers are stacked like jade. After death, due to drying and shrinkage, the color disappears and becomes monotonous brown. Larvae is flat and spiny, with forked appendages at the back end, which are attached with feces and debris.
