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
Hudson Hornet more ornamentation to the cars, including fender "finettes" atop the rounded rear quarter panels for 1957, as well as very unusual twin-fin trim on top of both front fenders. The price was reduced and the power was increased by way of AMC's new V8 that was rated at with a four-barrel carburetor and dual exhausts. Consumers reacted by buying only 4,108 units. Production of the Hornet ended on June 25, 1957, at which time the Hudson marque was dropped and all of AMC's products took the "Rambler" name. The 1951 Hudson Hornet was selected as the "Car of the Year"
