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 Bald Eagle's Nest or "Wapalanewachschiechey". The identity of Bald Eagle is unclear though. One chief with that name, who was "friendly and respected" was murdered on the Monongahela River in 1773. Another Bald Eagle, for whom the historic record is less clear, is traditionally supposed to have been the leader of raiding parties against white settlers on the West Branch Susquehanna River during the American Revolutionary War. He killed a brother of Samuel Brady near Williamsport in 1778 and Brady killed him on the Allegheny River in what is now Clarion County the next year. In any case, Bald Eagle
