Adult cabbage looper, Trichoplusia ni (Hübner). Photograph by Lyle J. Buss, University of Florida. During the adult stage, which averages 10 to 12 days, 300 to 600 eggs are produced by females (Shorey 1963). Moths are considered to be seminocturnal because feeding and oviposition sometimes occurs about dusk.
Why does the cabbage looper die at high altitude?
This is likely due to the residual effects of a nuclear polyhedrosis virus, which is quite lethal to this insect. The cabbage looper is highly dispersive, and adults have sometimes been found at high altitudes and far from shore.
