N2  - Searching and predatory behavior of the first, second and third nymphal instars of Sphodromntis viridis Forskal were examined towards all aphid stages of the cotton aphid, Aphis gossypii Glov. The time spent in searching, feeding and resting was recorded. The mean number of the preys consumed and the predation rate of each predator's instar was recorded. Proportion of the searching time was correlated with the predator's instars as well as the prey stage. The predator spent more time searching for early prey stages in comparison to less time searching for the late stages. The predater's instars were found preying on all the aphid stages. The high predation rates of the 1St, 2lld and 3rd predator's instars were obtained on the 2nd, 3rd, and adult aphid preys, respectively. This study might provide information on the predation behavior of the predator, S. viridis towards A. gossypii that may shed more light on the predator as a biological control agent
