Figure 1 with 1 supplement
Antennal responses to changing airflow.
(A) Inter-Antennal Angle (IAA) is measured by digitizing 4 points (red circles) on the antennae in all frames. (B) Groundspeed is obtained by tracking Point#2 (from A) which is static relative to …
Figure 1—figure supplement 1
Antennal responses to changing airflow.
(A) IAA values at 0.5 m/s airflow for a tethered (blue plot) and freely-flying honeybee (red plot). IAA values are maintained for all 250 frames for tethered bees (Mean=96°, S.D.= 0.8°) and …
Figure 2 with 2 supplements
Antennal responses to changing temporal frequency of optic flow.
(A) IAA response to optic flow in tethered bees. Bees were positioned central and at 10 cm from the two screens separated by 2 cm at the apex. (B) Sample IAA response to linearly increasing (red) or …
Figure 2—figure supplement 1
Antennal responses to changing optic flow rates.
Data for two additional individuals. Figure 2—figure supplement 1A–D show data from one individual and Figure 2—figure supplement 1E–H for a second individual. (A and E) IAA responses of linearly …
Figure 2—figure supplement 2
Antennal responses to changing optic flow rates.
(A) Raw data for response of tethered flying bees to changes in optic flow. Each colour represents in the plot the same individual as the corresponding colour in Figure 2I. (B) Raw data for response …
Figure 3
IAA responses to combinatorial stimuli.
(A) IAA response curve of a tethered bee to changing airflow (blue) and optic flow (red). Regime A represents the combination of low optic flow rate and airspeed (temporal frequency=0.3 cps; …
Figure 4
IAA responses to changes in optic flow in presence of constant airflow (A, B), and to changes in airspeed in presence of constant optic flow cues (C, D).
(A) IAA responses to optic flow rates varying from 0 to 1.8 cps in presence of still air (IAAOp; solid green line vs. steady 1 m/s airflow (IAAW+Op; dotted green line). Mean difference between IAAOp …
