The invasion of North America by the emerald ash borer (EAB, Agrilus planipennis) has devastated ash (Fraxinus spp.), especially in areas where the beetle has been established for multiple years. In southeastern Michigan, for example, ash mortality approaches 100%. Such mortality fundamentally changes stand structure and undoubtedly has severe consequences for ash dependent species. Unfortunately, the severity and rapidity of ash mortality has precluded appropriate biodiversity studies in the most heavily infested regions. Until very recently, New York State has been free of EAB infestation and thus offers opportunities to study ash dependent species prior to the arrival of this exotic insect. In 2009, we conducted a study in riparian and wetland ash stands at multiple sites in New York. We focused on moths as they are a well described and relatively easy to identify taxa. In addition, at least 20 species of ash specialists have been identified. Adults were sampled using a blacklighting grid and larvae were collected using pole-pruners and a drop sheet. All collected larvae were reared in the laboratory to a stage that permitted accurate identification. Statistical comparisons of species compositions were made among sites. This study will serve as an important benchmark with which to assess the impact of EAB or potentially restore damaged ecosystems in the future.
