In the Great Smoky Mountains National Park (GRSM), eastern hemlock is an important part of the forest ecology and plays a vital role in the lives of many organisms. Eastern hemlock in the GRSM is now threatened by an invasive species, the hemlock woolly adelgid (Adelges tsugae), which has caused tremendous decline of hemlocks in the northeastern United States. This poster describes the biology and seasonality of this invasive species, which was first recorded in the GRSM in 2002. Biology and seasonality data will be compared with life history data from other parts of the United States.


Species 1: Hemiptera Adelgidae Adelges tsugae (hemlock woolly adelgid)
Species 2: Coleoptera Coccinellidae Harmonia axyridis (multicolored Asian lady beetle)
Keywords: invasive species
