^aCysteine peptidase counts for each insect are based on latest gene annotation from Genbank, as assessed on 07/02/2017
^bThe ‘≥’ symbol indicates greater than or equal to
^cFigures in parentheses indicate total number of transcripts for a given gene family identified in H. halys transcriptome
^dThere was single transcript each for Cathepsin-J and Cathepsin-O identified in H. halys transcriptome, which are not indicated here
