Yellow head bumblebee

Bombus flavifrons


Bombus flavifrons is a robust bumblebee; the queen has a body length between 13 and 16 millimetres (0.51 and 0.63 in) and a wing span of 27 to 34 millimetres (1.1 to 1.3 in), the male is 11 to 12 millimetres (0.43 to 0.47 in) in length with a wingspan of 25 to 26 millimetres (0.98 to 1.02 in), while the workers have body lengths from 9 to 12 millimetres (0.35 to 0.47 in) and wingspans from 19 to 27 millimetres (0.75 to 1.06 in).[2] The Yellow head bumblebee has a dense, untidy fur. The head is yellow with black hairs intermixed on the posterior part,[2] the thorax has a mixed black and yellow colouration, often (always with the queen) with a black, central field. The first three terga (abdominal segments) are yellow, on the females often with a black, central field on terga 1 to 2. Terga 4 and 5 are red, and the tail black, sometimes with yellow fields.
