B.S.P. (Pinaceae), seed orchard located in New Brunswick, Canada. Trends in stage-specific survival were similar for both years. Most individuals died during the second-instar stage, we suspect mostly because of failure to establish. The lowest stage survival occurred during the prepupal and pupal stages, due primarily to predation by ground-dwelling invertebrates. Copyright © Entomological Society of Canada 1999 Fidgen L.L.
