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
USS Hornet (1865) in the Chesapeake Bay squadron. In October 1865, "Hornet" escorted the Confederate ironclad CSS "Stonewall" from Cuba to the United States. "Hornet" was decommissioned on 15 December 1865 and sold into private ownership in 1869. After the war "Hornet" was involved in several filibustering expeditions to Cuba under the names "Hornet" and "Cuba", including an unsuccessful mission in January 1871 to deliver weapons and ammunition to Cuban rebels during the Ten Years' War.
