Long-Winged Planthopper

About the Long-Winged Planthopper

Proutista moesta is a common species of planthopper from the family Derbidae, tribe Zoraidini. It is found in tropical parts of Asia from India to southern parts of China, some islands in the western Pacific (Taiwan, parts of Japan, Philippines, Guam, parts of Northern Marianas, Palau, parts of the Federated States of Micronesia, Indonesia, Papua New Guinea), as well as in the Indian Ocean (Seychelles, Maldives). There is also a record from eastern Africa, a possible recent introduction. P. moesta can be common on crops like oil palms, coconut palms, sugarcane and several cereals, where it sucks the sap from the plants. It is often regarded as a pest of these crops, a vector of phytoplasma diseases and a biosecurity risk in countries outside its distribution range. Males of P. moesta are smaller (around 6.9 mm) than females (around 7.6 mm) when measured from the tip of the head to the end of the forewings. The forewings alone have a length of around 6.1 mm for males or around 6.6 mm for females. The colour is predominantly black, but the legs, antennae, facial ridges and the rostrum are yellowish to light orange. The ridges on the mesonotum and the clypeus are whitish to light yellow and the body has scattered white dots. The black forewings have some clear patches, mainly along the costal margin and in the distal half between the hind margin and the media vein. When at rest, the insect raises its wings above the body and spreads them out at an angle of about 60°. Wikipedia →
