Bat Fork Bog Plant Conservation Preserve, located in Henderson County, North Carolina, is considered an example of a Southern Appalachian Mountain Bog. Across North Carolina this broadly defined habitat has high conservation significance due to the presence of a number of rare flora. However, very few examples of this wetland habitat remain intact, even those that are protected. In this paper, we describe the hydrology of Bat Fork Bog and efforts to restore this unique site.

Exploitation of the hunting behavior of the solitary wasp Cerceris fumipennis is proving to be a useful method for detecting pest Buprestidae as well as for documenting buprestid diversity in eastern North America. Here we review prey carriage mechanisms in the species, and conclude that variation in prey carriage is correlated with the spectacular size range of their buprestid prey (4.9-22.3 mm length). Small prey items, including Agrilus species, are transported with the aid of a specialized morphological structure on the fifth metasomal sternite ("buprestid clamp"), resulting in a distinct curved posture during fight. Analysis of prey items from C. fumipennis in North Carolina in 2014 indicates that 30% of collected Agrilus spp. were not paralyzed prior to wasp arrival at the nest, and suggests that the buprestid clamp may function to prevent the escape of active small prey. Recognition that the curved fight posture of a female approaching her nest is a signal that she may be carrying a beetle in the genus Agrilus can improve efficiency of biosurveillance for pest Buprestidae.

Cerceris fumipennis Say is a solitary, ground-nesting wasp that preys exclusively on beetles in the family Buprestidae, including the invasive insect pest, emerald ash borer (Agrilus planipennis Fairmaire). Understanding patterns of C. fumipennis prey collection over time may improve use of the wasp as a biosurveillance tool for locating pest Buprestidae of economic concern. Here, we report on variation in prey capture by C. fumipennis at two sites in North Carolina over a 4-yr period. In total, 466 beetles were collected from the wasps from 2010 to 2013; these comprise 35 species, four new state records, six new prey records, and three native pests. Changes in prey capture from year to year at both sites suggest the importance of continued biosurveillance at sites with known wasp aggregations as emerald ash borer and other invasive pests spread into and throughout North Carolina. © 2014 Entomological Society of America.

The solitary, ground-nesting crabronid wasp Cerceris fumipennis Say excels at detecting buprestid diversity in a given geographic area, and after the introduction of the invasive pest emerald ash borer (Agrilus planipennis Fairmaire) to the United States in 2002, has been developed as an effective tool for the biosurveillance of pest Buprestidae in eastern North America. Here we report records of Buprestidae collected from foraging C. fumipennis in 13 North Carolina counties over the course of three seasons (2009-2011). Nests of the wasp were located, and beetle prey collected from foraging females in three geographic regions, with a concentration on the western, mountainous area of the state. In total, 909 beetles were collected, comprising 52 buprestid species that included eight native pests and 17 species of Agrilus. Our results emphasize the utility of C. fumipennis in documenting buprestid biodiversity and in detecting forest pests. Eight new state records and five new prey records for the wasp are here recorded. © 2013 Entomological Society of America. © 2013 Entomological Society of America. Source

Plant host specificity of prey buprestid beetles was used to estimate the minimum distance of hunting flights by the solitary fossorial wasp, Cerceris fumipennis Say. Plant hosts of the 5 beetle species investigated were each found at less than 200 m of the wasp nesting area. Although these results indicate neither average nor maximal hunting range, they suggest a working hypothesis that foraging in close proximity to the nesting site may be the norm. Source
