front_leg.jpg - flight_muscles
A worker with the top cuticle removed from the thorax to show the thoracic muscles. The middle two (looked like one but it is ctually two) are the longitudinal muscles, which run from the head direction to abdomone direction. While the two near the wings are the verticle muscles. - claws_arolia
Closeup of the tip of a leg, showing the two claws on the sides and a soft pad (arolium) in the middle. The claws allow workers to grab on rough surfaces, while the arolium works as a suction pad to hold on to smooth surfaces. - bee_hair2
Closeup of hairs on the thorax of a worker bee. Notice that each hair is branched (plumose), enabling it to trap pollen grains more effectively.
