Bombus pascuorum males

This is a Bombus pascuorum male foraging on scabious. It is fairly easy to see he is a male if you look at his rear leg you can see it is narrower and has no pollen basket.

Below you can see the head of the same bumblebee. This shows another way of recognising males. Just below the antennae they have a very prominent tuft of hair. In pascuorum it is the same ginger colour as the rest of the body. In many other species it is yellow.
