Abstract
Curculionidae (weevils) frequently are recognized as favoring moist environments and wetland vegetation. To better understand the relationship between wetland type and the presence of curculionid species, twenty-four isolated wetlands (previously characterized as marshes, savannas or forested swamps) were sampled. Seventeen genera and 27 species were identified. Indicator species analysis revealed an association between the genus Dirabius and marsh habitat. NMS (Non-Metric Multidimensional Scaling Ordination) found a significant 2-dimensional solution to abundance data. Auleutes nebulosus, Lissorhoptrus simplex, Notiodes laticollis, Rhinoncus longulus, Sphenophorus minimus, and an unidentified species of Dirabius and Listronotus were associated with marshes. Swamps were characterized by their absence of Curculionidae. Savannas were intermediate between marshes and swamps. Marshes, with their diversity of vascular plants, appear to provide more suitable habitat and possess characteristics that allow curculionid populations to persist in the landscape.
