sentences:  This means that development takes longer over winter for these insects as compared to spring and summer times.Since development is very closely related to temperature, researchers in the study also concluded that the number of leafhopper generations produced in a year may be related to the seasonal temperatures of their habitat.They found that under lab conditions, where the leafhoppers were raised in optimal temperatures of 95 °F, as many as 15-16 generations of leafhoppers could be produced per year.
