Fig. 8. Summary of all the results of the force response data. The influence of the
load cell dynamics was compensated for the respective measurement data,
according to Eqn 4 and Eqn 5. We represented the characteristics of the
corrected force response (
)
in terms of amplitude
(
) and
phase
(
).
(A)
is mainly distributed between 0.1 and 0.5 at each 
, and the mean values
are approximately 0.3 for all . The bumblebees did not change
throughout . (B) In contrast,
clearly decreases with increasing . When is lower than 3.6 Hz
(22 rad s-1), 
F0 in all the data is
positive, i.e., the phase of
is earlier than that of
zv. When is around 3.6 Hz (22 rad s-1),
the mean value of
is approximately 0°, meaning that the phases of
and zv
are almost synchronized. When the visual stripes oscillate at 7.4 Hz (46 rad
s-1),
in all the data is negative, i.e. the phase of
lagged behind that of
zv.
