The scientific name of the leaf hopper or pyrilla is Pyrilla perpusilla Walk.
Pyrilla perpusilla, commonly known as the sugarcane planthopper, is a planthopper in the family Lophopidae. It is native to Asia where it feeds on grasses and other plants and is a major pest of sugarcane and sorghum.
Adult female P. perpusilla lay small batches of eggs on sugarcane leaves, mostly on the underside but sometimes on the upper surface, and during the winter, inside the leaf sheath. The eggs are laid in four or five rows and are protected with filaments of whitish wax protruded by the female. The planthopper feeds on its host by inserting its stylet into a leaf and sucking out the phloem sap.
