PLATE 1.32. QUEEN MIDDLE AND HIND LEGS

Photomontage of the middle, or mesothoracic (left), and hind, or metathoracic (right) legs. At the leg base the first segment, the coxa, is almost completely obscured by the hairs of the mesothoracic pleurites. The next segment, the trochanter, is visible, extending (horizontally) to articulate with the larger femur. The tibia joins the femur (at the "knee") and extends downward. The mesothoracic tibia is about as wide as the femur, but the hind tibia is flattened and much broader. The second downward-projecting segment is the basal tarsomere, which is clearly much larger than the other, more distal tarsal segments. In the queen the metathoracic basal tarsomere lacks the pollen collection apparatus of its counterpart in the worker (see Plates 2.28, 2.29, 2.30, and 2.31). Four remaining tarsal segments are present; the last one (pretarsus) is elongate and bears claws. These first four tarsal segments have no muscles, but a common tendon traverses all of them and inserts into the flexor muscle of the pretarsus. ( x 28)
