Chapter 3 Opener A leafcutter ant worker carries a leaf back to the colony while a much smaller
worker rides on the leaf to protect her sister against parasitic flies

Figure 3.28 Mating males of the damselfly Lestes viridis (red bars) have more symmetrical wings
than unmated males (orange bars)
Brown et al. 2005
a, Mean dance ability of
males (filled bars throughout)
and females (open bars
throughout) by level of bodily
symmetry. Error bars
represent 95% confidence
intervals. P values for withinsex are shown. b, Mean
strength of symmetry
preference (that is,
evaluations of asymmetrical
dancers subtracted from
evaluations of symmetrical
dancers) by sex of dancer
and sex of evaluator. Error
bars represent 95%
confidence intervals. P value
at top of panel indicates
significantly greater female
than male evaluator
preference for symmetrical
male dancers.

Males learn to avoid
orchid over time
(quicker decline in
visits than for visits to
females)
