METHODS
Experimental assessment of arthropod predation:
Twenty artificial caterpillars made from green plasticine (diameter 3 mm, length 20 mm) were placed 
at ground level on open herbaceous vegetation for a 2-d period. Arthropod attack marks on caterpillars
were assessed in the field, and those caterpillars brought to the lab were double-checked (raw data).
From the number of assessed caterpillars with and without arthropod attack marks, arthropod predation
rates were calculated and data aquired in deviation from the protocol was excluded (processed data).
For details see 'Fricke et al predation data processing' and address the manuscript.

Data processing (standardization): 
> beginnning of the experiment between 10th and 25th May 2019
> exposure duration 42–54 hours
> assessment of attack marks on at least 16 (out of 20) artificial caterpillars
