In this study we present biological cycle aspects of Terpsis quadrivittata Champion, 1893 (Chrysomelidae: Cassidinae: Mesomphaliini). Observations “In Situ” was made along a five-kilometer transept, with three lianas "bejucos" of Ipomoea philomega (Vell.) House (Convolvulaceae); known as host and food source for larvae and adults of T. quadrivittata. In each liana the presence of adults and the three stages of insect development were recorded: eggs, larvae (I, II, III and IV), pre-pupa and pupa. A total of 67 eggs found in three lianas of I. philomega were collected and observed. Observations were made of the development and average duration of the four immature stages of T. quadrivittata under laboratory conditions, which were interrupted when the insects reached the adult stage. All T. quadrivittata ovipositions observed during this study were viable. On the other hand, the average duration of each stage was 7 days for eggs; 4 days for the larval stage I; 3 days for stage II; 3 days for stage III; 4 days for stage IV; 2 days for the pre-pupa stage and 7 days for the pupa stage, with a total duration of the life cycle of T. quadrivittata of 30 days.
