Coastal forests are facing threats due to rising sea levels, increased storm severity, and land use change. These factors stress trees within coastal ecosystems, potentially predisposing them to attack by insects. In North America, two insect species of concern that pose threats to for coastal forest health are the native baldcypress leafroller (BCLR), Archips goyerana Kruse (Lepidoptera: Tortricidae), and non-native Japanese cedar longhorned beetle (JCLB), Callidiellum rufipenne Motschulsky (Coleoptera: Cerambycidae). Baldcypress leafroller has been reported from Mississippi and Louisiana, with defoliation only reported from the latter where increased flooding has stressed host trees. Through widespread trapping efforts, I found that BCLR occurs north into Arkansas and northeast into Delaware. I conducted environmental niche modeling that indicated that climatically suitable habitat in the United States is primarily in the southeastern United States, but that climatic suitability of the southeastern United States will increase and expands northwards. For JCLB, I found that interceptions of this insect of ports of entry in North America have remained low since the implementation of ISPM-15, and that most interceptions occur on wood packaging materials from the insect’s native range. Environmental niche modeling for JCLB indicated that climatically suitable areas were more prevalent in in the northern hemisphere under current and future climatic scenarios, but that poleward shifts in suitability are likely with ongoing climate change.
