Life cycle of the grasshopper Cornops aquaticum (Bruner, 1906) (Orthoptera: Acrididae: Leptysminae) is dependent on Eichhornia (Pontederiaceae). Experiments were carried outdoors during receding water, the Mating last for about 40 and 120 minutes. The ootheca has an average of 13.4 (+/- 3.2) eggs. Incubation lasted for 34.1 days (+/- 1.97). Mean durations of total development from egg to adult was 156.2 days, being 34.1 in the egg stage, 53.4 in the ninphal stage, and 68.7 in the adult stage. Nymphs (N) and adults (A) accepted only six aquatic macrophytes out of 13 species offered during 30 days; survived more time in Pistia stratiotes (N = 43 %, 30 days and A = 1 %, 27 days) and Pontederia sp. (N = 85 % and A = 40 % until 24 days) than Limnobium sp. (N =13% and A =10 % until 12 dias), Ludwigia sp. (N =3 %, 24 days and A =15 %, 9 days) Azolla sp. (N =35 %, 9 days and A =15 %, 12 days) and Paspalum repens (N =3 %, 21 days and A =5 %, 24 days).
