Variations of secretions of the cephalic part of the labial glands from four different subspecies of Bombus terrestris, B. t. terrestris, B. t. lusitanicus, B. t. sassaricus , and B. t. dalmatinus , were investigated. 95 compounds were detected in the whole data set: 54 in B. t. terrestris , 54 in B. t. lusitanicus , 48 in B. t. sassaricus , and 44 in B. t. dalmatinus. The ( E )‐2,3‐dihydrofarnesol is the main compound in B. t. dalmatinus and B. t. sassaricus , while it is dihydrofarnesyl dodecanoate in B. t. terrestris and B. t. lusitanicus. A principal component analysis produced a pattern showing three well distinct groups corresponding to dalmatinus, sassaricus , and terrestris+lusitanicus.
