While the Southeastern United States can roughly be divided into a wet
season (winter/spring) and a dry season (summer/fall), the summer is usually
punctuated by brief (weekly) thunderstorms that can cause short term
flooding. I was under the impression that S. psittacina grew in wetter
habitats that other Sarracenia species; if so they would be more regularly
innundated. Also, the aquatic juveniles of many insects "crawl" on the
underwater substrate and could be trapped by S. psittacina pitchers.
