Metabarcoding of arthropod bulk sample
The insect bulk sample was sieved into 2 size fractions S (<4mm) and L (>4mm) and the size fractions were pooled 9:1 (S:L), resulting in one pooled library. An amplicon library was created with fwhF2 (Vamost et al. 2017) and FolDegenRev (Yu et al. 2012) primers.
