![]() The nutrition of caterpillars, translated into pupal weight, appears to have a positive effect on the longevity of resultant adults. ![]() Males lived on average longer than females, and moths from heavier pupae lived longer than their smaller siblings. A glimpse into the genetic component offered by using two broods suggests that one can expect to find greater variability in longevity between different populations of this species. On a diet of 6% sugar water or Gatorade®, a quarter of the moths survived for one month or longer, with a maximum survival of 50 days. In the present study, we evaluated the longevity of the chemically defended Ornate Bella Moth, Utetheisa ornatrix, using a sample of 214 individuals from two broods. Most butterflies and moths, with the exception of Heliconius, live only a week or two in their non-hibernating state.
