Data on movement and immobility duration (s) for antlions on the three substrates: Paper, Shallow sand and Deep sand (uploaded as a separate excel file in the SI due to its size).

ALid: antlion identification number, Weight_g: antlion weight (g), Date: date of experiment; Sess: session 1 (in the morning) or session 2 (at midday or in the early afternoon) of the experiment on a given date, Treat: treatment substrate—Paper, Shallow sand (2.3sand) or Deep sand (4.6sand), Quad: quadrant in the 2x2 grid of four Petri dishes filmed simultaneously in which the antlion was dropped, Videos: number of videos of 22min31s duration with 10s-intervals between them that covered the first up to 16 immobility and movement periods for the antlion or up until it reached the arena wall, ArrT_s: arrival time (s) or the time when the antlion landed onto the substrate after being dropped from its individual vial, StTM1_s: start time for movement 1 (and similarly for all subsequent movement periods up to movement 16), I1dur_s: duration (s) of immobility period 1 (and similarly for all subsequent immobility periods up to immobility 16), EnTM1_s: end time for movement 1 (and similarly for all subsequent movement periods up to movement 16), M1dur_s: duration (s) of movement period 1 (and similarly for all subsequent movement periods up to movement 16).
