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
AMC Hornet expenses should a car require overnight repairs when the owner is away from home. Suggested prices began at $2,298 for the base model two-door sedan with the more popular new hatchback going for $2,449. All four versions of the Hornet were mostly carryovers in 1974, with minimal trim changes. The front bumper lost its full-width vinyl rub strip but gained two rubber-faced bumper guards. A larger, energy-absorbing rear bumper was added to meet new 5 mph safety standards and the license plate was moved up to a position between the taillights. All Hornet body styles saw sales gains compared to
