The venom glands of both workers and ergatoid queens of the ant Leptogenys diminuta contain 4-methyl-3-heptanol and a mixture of esters of this alcohol and long-chain fatty acids. Only the higher proportion of 4-methyl-3-heptanone in the queens represents a chemical difference between the castes. The Dufour gland secretion of workers and queens, however, shows considerable differences. Both share a series of long-chain hydrocarbons with 9- and 7-pentacosene as the major substances of the secretion but are otherwise differentiated by the presence in the workers only of three farnesene isomers, whereas queens contain a wide range of substances. The mated queen had a very complex mixture of hydrocarbons, esters and terpenes. These substances were also present in the virgin females but in smaller quantities.
