Black planthopper (Ricania speculum)

Ricania speculum can reach a length of about 8 millimetres (0.31 in), with a wingspan of about 15 millimetres (0.59 in). These planthoppers have dark brown wings with central wavy horizontal bands and irregular transparent patches of different sizes. The precostal area of the forewings shows dense transverse veinlets and the costal margin is distinctly convex near the base. In males the tip of the abdomen is pointed, while in females is rounded. The final instar nymphs are white with dark brown markings and waxy secretions on the abdomen. (tekst Wikipedia)
