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. The adult P. perpusilla has an elongated snout with piercing and sucking mouthparts, and a soft body, and is a yellowish-brown colour. Males have a wing-span of about 20 mm (0.8 in) and females are slightly smaller, averaging 17 mm (0.7 in). The eggs are ovoid, white to yellowish-green and about 2 mm (0.08 in) long. The nymphs are creamy-white and each instar stage has long filaments projecting near the anus.
P. perpusilla is native to southern Asia and occurs in Afghanistan, Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand and Vietnam. Besides sugarcane, this planthopper has been found feeding on other host plants, and breeding on some of them. These include maize, sorghum, pearl millet, barley, bitter melon, okra, Vietnamese luffa, watermelon, squash, rice, wild oat, pea and Indian thorny bamboo.

GBIF citizen-science records
It is estimated from how often the Sugarcane Planthopper is recorded against all the insects logged in New Delhi (8 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
