Fig. 1. Dancing and sleeping bees. (A) A dance consists of waggle phases
which code information about a location (e.g., a food source). Pictured are
two waggle phases, shown as sequences of jagged lines, connected by
a long, curved path. The angle of a waggle phase relative to the vertical is
the dance angle, and corresponds to the flight angle to a food source relative
to the sun’s azimuth. Here, 1 and 2 represent two consecutive dance
angles. The duration of a waggle phase corresponds to the distance to
a food source, and is the time taken for a dancer’s head to traverse the
distance of the waggle (red dots mark the extent of a waggle phase). SD of
dance angles and CV of durations of waggle phases per dance were our
precision measures of direction and distance information signaled by dancers.
(B) A tagged and marked sleeping bee. (C) Bee sleeping inside a cell.
Sleeping bees can be identified by their dorsoventral discontinuous ventilatory
motions, represented by arrows. The images of sleeping bees have
been modified to highlight sleeping individuals and display metal tag (orange
circle on thorax) and paint markings (blue and yellow on abdomen
