Survey of Semiothisa fraserata (Geometridae) and Gazoryctra sciophanes (Hepialidae) in the Southern Appalacians
Grehan JR. 1998. Survey of Semiothisa fraserata (Geometridae) and Gazoryctra sciophanes (Hepialidae) in the Southern Appalacians. United States Fish And Wildlife Service. Asheville, NC
Results of a survey for two moth species. Work on the survey was carried out in several areas including Great Smoky Mountains National Park and Blue Ridge Parkway. Results: 'No specific management policies are necessary at this time. Future surveys will be desirable if the spruce/fir habitat undergoes further decline'. Light trap and flight intercept moth surveys at multiple sites along Blue Ridge Parkway, Great Smoky Mountains National Park, and Mount Mitchell during July 1995 and 1996. Moths were trapped at several sites in North Carolina within a day's drive of Asheville, and two sites in Virginia in the Mount Rogers Recreational Area. Sites were chosen for accessibility to spruce/fir forest (with the exception of Licklog Gap chosen as a control site outside the spruce/fir habitat) from the road for light and sticky traps. The Mount Rogers National Recreation Area in Virginia was selected to determine whether the northern limit of G. sciophanes may be correlated with the northern limit of Fraser Fir forest. Due to time and budgetary constraints sampling was limited to a single night. Site descriptions: Richland Balsam Mountain, Waterrock Knob, Roan Mountain, Mount Mitchell, Smoky Mountains National Park(Indian Gap, Newfound Gap),Mount Rodgers National Recreation Area.
