In Samia cynthia ricini, the two biliverdin-binding proteins (BBP-I and BBP-II) from larval hemolymph share only 48% identity in their N-terminal 50 amino acid residues. BBP-II is likely identical to the biliprotein isolated from the molting fluid at pupation from the same insect ( Saito, 1993, 1998a ).
