Bald-faced hornet hydrocarbons serve as a barrier to moisture diffusion and thus prevent dehydration in wasps. Cuticular hydrocarbon profiles vary over species and nests, and so cuticular hydrocarbons are a proposed mechanism for nest-mate recognition. Worker and queen cuticular lipids have similar components, but their distributions differ dramatically, implying that cuticular hydrocarbons also play a role in caste differentiation. The following lipid profiles were determined from specimens collected in the summer and early fall of northeastern Georgia in 1989. The dominant hydrocarbons recovered from the cuticles of workers were n-alkanes and methyl branched and dimethyl branched alkanes with a C27 or a
Bob Stratton Bald accessible via the Stratton Bald Trail (FS Trail 54), which connects to the Benton MacKaye Trail and the Cherohala Skyway. Bob Stratton Bald Bob Stratton Bald, often referred to as Stratton Bald, is a grassy bald in the Unicoi Mountains located in the Joyce Kilmer-Slickrock Wilderness in the Nantahala National Forest. Its elevation is approximately 5,360 feet. The bald is named for Robert "Bob" Stratton (1825-1864), whose family lived on the bald. The bald is subdivided into two smaller balds: Stratton Bald (elevation 5,360 feet), and Bob Bald (elevation 5,280 feet). Together, they make up Bob Stratton Bald. It is
