The functional response of the three larval instars of predatory green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), fed the two spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae). First and second instars functional type II predator responses against T. urticae prey. Third instar showed type III functional response. The rate of the three larval instars of C. carnea attack was 0.0113, 0.061 and 0.057 respectively. Whereas handling time (T_h) of the three larval stages of C. carnea was recorded 0.5639 and 0.048 respectively 0.021h., on the other side, the expected maximum consumption (T/ T_h) of  three larval instat of C. carnea is 42.8, 500 and 1142 per day for adult T. urticae respectively. The results of this study showed that larvae of C. carnea, mostly the final instars, have well possibility to benefit from predation spider mites.
