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
HMS Hornet (1794) was in company with when they captured the Spanish vessel "Aguilla". In August 1802 "Hornet" came under the command of Lieutenant Robert Tucker. Next month Commander Peter Hunt replaced Tucker. In June 1803, "Hornet" was in Commodore Samuel Hood's squadron at the capture of St. Lucia. The squadron, including "Hornet", went on to capture Tobago on 25 June. On 3 September "Hornet" captured a Dutch ship, whose name was not recorded, that was carrying 410 slaves. Then in September Hood went on to take the colonies of Demerara and Essequibo from the Batavian Republic. On 20 September "Hornet", the schooner
