List of primers used in the present study: (1–6): cox1 primers used to amplify target and non-target prey; (7–8): New specific primers designed to amplify Eluma caelata; and (9–10): Primers used to amplify the cox1 region for the metabarcoding analyses.

DNA detectability half-life of the different body parts tested calculated with probit models, and 83% fiducial confidence limits calculated to compared half-lives.
Fig 2.
Abundance of reads of detected MOTUs in different body parts of D. verneaui 72 hours after feeding and in a positive control (a mix of 10 spiders recently fed).
The total number of reads obtained for each sample (after quality control) is shown above the bar plots. Relative abundance of reads (above) and relative abundance of log-transformed reads (below) are shown, for a better visualization of MOTUs detected in low abundances.
