Fig. 5. Experiment 3. Effect of spatial changes of pattern velocity on flight
speed. (A) Mean flight speeds when the pattern is static in the first half of
the tunnel and moving in the second half. (B) Mean flight speeds when the
pattern is moving in the first half of the tunnel and static in the second
half. In each case, the open squares and filled circles indicate mean flight
speeds in the static and moving sections, respectively. The solid line
represents a regression model of the data; the equation for this line is shown
on each graph. The error bars to the left of each data point indicate the
standard deviation for the stationary section (open squares); the bars to the
right of each data point indicate the standard deviation for the moving
section (filled circles). Other details are as in
