Isyndus reticulatus is a bivoltine assassin bug，living on trees，with five instars（Yi，2004）.Under laboratory conditions in Beijing，mature adults mate from late April to early May，and females lay eggs in early May to late June.From late May to August，nymphs of the first generation develop from eggs to fifth instar（Figs 15–21）.The peak of emergence of new adults（Fig.22）occurs in late July to early August.The first generation mates and lays eggs from late September to October.About twenty days later，the nymphs of the second generation appear and develop from early October to late December.Fifth instar appears in early December（Table 1）.The development durations of the same instar of the two generations are very similar，with the exception that adults of the second generation overwinter from January to March and live longer than those of the first（Table 2）.
