Abstract From the volatile constituents of the solitary bee species Panurgus banksianus Kirby and P. calcaratus Scopuli 31 compounds could be identified. The cephalic secretion of P. banksianus is a sex specific m ulticomponent mixture of terpenes and aliphatic carboxylic acid esters while P. calcaratus contains monoterpenes only. The major component in the Dufour’s gland secretion of P. banksianus is a macrocyclic lactone, eicosanolide, which is absent in P. calcaratus. In contrast, the new terpenoid ester, geranyl citronellate, is present in large amounts in the Dufour’s gland secretion of P. calcaratus.
