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) USS Hornet (1865) The USS "Hornet" (1865) was the fifth United States Navy ship to bear the name Hornet. She was originally the CSS "Lady Stirling", a blockade runner built by James Ash at Cubitt Town, London in 1864 for the Confederate States Navy.
