Seeking safety: Movement dynamics after post-contact immobility
Fig 5
Path (mm) and instantaneous speed (mms-1) over time for one of the antlions on each of the three substrates.
(a)-(b) Antlion 19 on Paper, (c)-(d) Antlion 21 on Shallow sand and (e)-(f) Antlion 6 on Deep sand; dotted black line: path from the spot in the centre of the arena where the antlion larva was dropped (Paper: light blue circle; Shallow sand: light green circle; Deep sand: light yellow circle) to the wall (Paper: red circle) or end of up to 16 moves (Shallow sand: pink circle; Deep sand: salmon pink circle) with superimposed stops (Paper: dark blue circle; Shallow sand: dark green circle; Deep sand: dark yellow circle) and displacement segments between stops (Paper: light blue line; Shallow sand: light green line; Deep sand: light yellow line); black line: instantaneous speed over time (s) calculated from the image-analysis track, cyan highlight: the superimposed observed movement periods up to reaching the wall or end of up to 16 moves.
