Morphometrics and wing-stroke frequency of bumblebees

D P ABROL

Abstract


A study of wing-beat frequency of Bombus asiaticus Morawitz and B. albopleuralis Friese shows that while the frequency varies between individuals and species, and is a function of body parameters, in general, the former has higher wing-beat frequency compared to the latter. B. asiaticus has greater weight and size than B. albopleuralis. Experimental results agree with theoretically computed values obtained from mass-flow theory.
