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
Bald Eagle Creek Path gave his name directly or indirectly to Bald Eagle Mountain, two Bald Eagle Creeks, the Bald Eagle Creek Path, Bald Eagle State Park, the Nittany and Bald Eagle Railroad, and Bald Eagle Township. In 1949, the Pennsylvania Historical and Museum Commission put up a historical marker on Pennsylvania Route 150 near the borough of Howard commemorating the path, which it called the "Warriors Path". Wallace's book "Indian Paths of Pennsylvania", originally published in 1964 and since updated, noted that many north-south paths were called Warriors Path, and called this Bald Eagle Creek Path. While the path no longer exists, several
