Hemlock woolly adelgid (HWA) is a devastating pest of eastern hemlock, and the most widely-released introduced natural enemy of HWA is Sasajiscymnus tsugae.  Initial releases of S. tsugae in the Great Smoky Mountains National Park were made in 2002, and since that time over 550,000 have been released in the Park. This paper presents the dispersal of S. tsugae from release sites into a non-release area, the seasonality of S. tsugae in this non-release area over a three-year period, and the coexistence of S. tsugae with another introduced predator, Laricobius nigrinus, and its native congener, L. rubidus.
