Data from short-term (20 min) experiment on the effect of color on behavioral exposure. Each row represents bout of movement by the caterpillar and the thermal image taken at the start of this movement, but in some cases the same row is replicated mulitple times if that action fit several categories (see "Action" field description below). Only the data from when the caterpillar first moved to shade was used in the final analysis. Caterpillar-specific fields (these fields are the same for all rows associated with a particular caterpillar and its trial): Date: date on whic trial was conducted (dd.mm.yy) ID: unique id number for tested caterpillar Family: ID number for family that the tested caterpillar came from (note that since this was a lab colony, families themselves may have been related to varying degrees), not used in analysis SignalSize: length of the caterpillar's orange band (in number of body segments) Mass: mass (in mg) of the caterpillar, weighed after the trial AirTemp: ambient air temperature (°C) in the room during the trial Plant: ID for the plant used in the trial (each plant was used in multiple trials) StartTime: Time of day when the trial started StartLocation: Position in which the caterpillar had come to rest when the trial started; possible values are "ground" (on the soil in the pot), "ground, curled" (on the soil and also curled up), "leaf" (on a leaf of the plant), "leaf, curled" (on a leaf and also curled up), or "mix" (on both ground and a leaf). StartShadeTemp: temperature (°C) of a shaded thermocouple on the soil of the pot (see methods) at the start of the experiment Image-specific fields (these fields are specific to a given movement my the caterpillar and the thermal image taken at the start of that movement): Action: the outcome of the movement bout captured by the thermal image. Potential values are: "first move" (the first time the caterpillar moved during the trial), "reach shade" (the first movment which ended in at least 20% shade, used for final analysis), "final move" (a movment which ended in at least 50% shade, used as alternative criteria for seeking shade and ending the experiment), "move" (additional movements that did not end in shade), "additional shade" (additional movements that ended in at least 20% shade, but less than 50%), "move to full" (movement after reaching 50% shade leading to full shade, did not consistently happen and not analyzed), "alt reach shade" (from cases where the caterpillar reached at least 20% shade, but then left, all excluded from final analysis), and "end" (additional picture taken at end of experiment, not movement, if the caterpillar never moved to at least 50% shade after 20 min). Note that "first move", "reach shade", and "final move" were identified for all trials, and in some cases represent the same data (for example, if the first time the caterpillar moved, it moved to >50% shade, this qualified as all three). ActionTime(min): the time (in minutes) since the start of the trial when the caterpillar began moving and the thermal image was taken ActionPic: id number for the thermal image associated with the movement ActionResult: where the caterpillar ended its movement, possible values are "ground" (on the soil in the pot), "leaf" (on a leaf of the plant), "leaf underside" (on the bottom of a leaf), "mix" (on both ground and a leaf), "rim" (edge of the pot), or "fell off" (fell off the pot). Not analyzed. ActionShade: amount of the caterpillars body that was shaded when it stopped moving, potential values include "none" (0%), minimal (<20%), partial (20-50%), majority (>50%, <100%), full (100%); "fell off" is a special category for when the caterpillar fell off the pot while moving. ActionShadeTemp: temperature (°C) of a shaded thermocouple on the soil of the pot (see methods) when the caterpillar started moving Exclusion: criteria for potentially excluding measurement from analysis, they are "FellOff" (caterpillar fell off the pot and did not resume moving within 15s when replaced, excluded), "FellOffResumed" (same as fell off, but resumed moving within 15s, so not excluded from analysis), "LeftShade" (left shade after previous movement into shade, excluded), "OutOfTime" (picture taken when trial ended after 20 min without reaching at least 50% shade) Notes: notes made by researcher during trial and image processing; not used to exclude individuals from analysis unless the met the specific criteria outlined in Exclusion field, or associated dependent variable measurement wasn't possible. ImageMin: minimum temperature (°C) in entire thermal image (used in calculating caterpillar temperature) ImageMax: maximum temperature (°C) in entire thermal image (used in calculating caterpillar temperature) CatActionTemp: mean temperature (°C) of the caterpillar in the thermal image taken when movement began (see methods for more details)
