This is a Flatid planthopper (Lawana imitata), or commonly known as White moth bugs, I found in Sha Tau Kok, northern Fanling, New Territories. It can also be found in China and Vietnam.
They live in trees. Adults are active from May to October. I think they look so elegant and beautiful, but farmers just hate them because they drink plant juices from stems to leaves to fruits. This species is considered a pest of citrus, tea, mango, guava, grape, lychee, and cashew.

白蛾蠟蟲, 紫絡蛾蠟蟬, Flatid planthopper (Lawana imitata)。
牠們住在樹上, 成蟲(成年的昆蟲)活躍於5月至10月, 我覺得牠們外型優雅美麗, 但農夫很討厭牠們, 因為牠們會吸食農作物莖部的汁液, 以至葉子及果實。牠們被認定為某些植物的農業害蟲 ,包括橙, 茶, 芒果, 石榴, 葡萄, 荔枝以及腰果。
