Sugarcane Spittlebug (Callitettix versicolor, 稻赤斑黑沫蝉).
A glossy black bug with four white spots and two to four red spots, they are easy to find when they are resting on summer leaves. This spittlebug is also a great destroyer of rice and maize crops throughout south-east Asia. They make themselves conspicuous climbing to exposed sun-drenched positions in the overgrowth along the Xiang river, particularly in July and August, though I still chance upon them now when walking about there. They also leave long pallid yellow spots on the plants they have fed upon.
