Cornops aquaticum is a semiaquatic species of grasshopper native to the Neotropics, from southern Mexico south to central Argentina and Uruguay.^[1] It feeds and breeds exclusively on members of the aquatic plant family Pontederiaceae, especially water hyacinth (Eichhornia crassipes), and is being investigated as a possible biological pest control agent for the water hyacinth in countries where that plant is invasive.^[2]

Although its semiaquatic behavior is unusual, it is not unique. In South America alone there are more than 50 species of orthopterans that are associated with water, including a few relatively well-known species like Paulinia acuminata, which is used for control of the plant Salvinia molesta.^[3]
