Amrasca biguttula, commonly known as the cotton jassid,[1] is a subspecies of leafhopper belonging to the subfamily Typhlocybinae of family Cicadellidae.

In India, this jassid feeds on sap from a wide range of plants including cotton, okra, eggplant, Hibiscus rosa-sinensis, and sunflower throughout the year, and on pigeon pea and cowpea during the monsoon season.

[5] Heavy infestations on cotton, okra, and sunflower make the leaves turn yellow, curl up and fall off.

The insects also secrete honeydew, and sooty mould often grows on this, restricting the amount of light reaching the plant's photosynthetic surfaces and reducing the yield.

[6] A number of natural enemies help to control populations including ladybirds, predatory lygaeid bugs, and several species of mantis.
