Eggs required 5.3 days to hatch; the 1st instar lasted 3.5 days, the 2nd 3.0 days, and the 3rd 3.8 days, giving a larval stage of 10.3 days. The combined pre-pupal and pupal stages lasted 9.9 days. Larval size and head capsule widths were measured for each instar. Males lived a mean of 55 days and females a mean of 65 days. The pre-oviposition period averaged 5.4 days. A mean of 687 eggs was laid by each female, the maximum being 1,175 eggs. Most eggs were laid 10–40 days after emergence; oviposition was almost entirely nocturnal. Larvae fed freely on noctuid eggs, and adults were predaceous on cabbage looper eggs, Trichoplusia ni (Hübner), but not the cabbage aphid, Brevicoryne brassicae (L.).Read More
