The green lacewings are important predators and are found in several agroecosystems. The temperature is one of the decisive factors for the development of insects, and there is an acceptable variation gradient for each species. Therefore, the purpose of this study was not only to check the influence of different temperatures on the embryonic and post-embryonic development of Chrysoperla raimundoi, as well as check the consequences in the different generations. The immature stages were reared at four different environmental conditions, three of them with constant temperatures (19,0, 25,0 e 31,0ºC) and the fourth rearing place was external to the laboratory without control of the abiotic factors. The duration of the embryonic period, first, second and third larval instar, pupal stage, and from egg to adult were evaluated; also the survival rate of each instar and stage and the emergence rate were calculated. The embryonic and post embryonic development differed between the generations F2 and F4. Also, the influence of different temperatures for the generation F2 among individuals created at 31,0ºC showed reduction on the development rate regarding the other two environments. It was possible to observe that the generation F4 has its development influenced by different temperatures, and the 19,0ºC temperature prolonged its development.
