The age-dependent changes in the composition of triacylglycerols (TAG) in the fat bodies of bumblebee males were studied using HPLC/MS. Two related species (Bombus terrestris and B. lucorum) were compared, with the age of the males being 0–30 days. The total amount of TAG in B. lucorum was about 2.7 times higher than that in B. terrestris. The composition of fatty acids in TAG differed between B. terrestris and B. lucorum: 14:0, 7 % and 14 %; 16:0, 20 % and 44 %; 18:3, 62 % and 23 %; 18:1, 3 % and 8 %, respectively. In B. terrestris different age classes differed in their TAG composition while in B. lucorum the TAG did not change substantially during the male’s life.
