Fig. 2. The responses of honeybees when presented with a choice between a flower
occupied by a manipulated UV-absorbing crab spider and a vacant flower (left;
N=28) and a choice between a flower occupied by a naturally white
crab spider and a vacant flower (right; N=25; data taken from
Heiling et al., 2003). The
data show the percentage of times that honeybees first landed on the
spider-occupied flower (black bars) or first landed on the vacant flower
(white bars). Each bee was tested only once. **P<0.01.
