The key difference between dry silks from moths and butterflies and wet silks from caddisflies is that the serines in the silk from caddisflies are "phosphorylated," meaning phosphates are added to the serines as the fibroin silk protein is synthesized.

He found the caddisfly silk is a fiber made of large proteins named fibroin (fye-bro-in) with an amino acid named serine making up a fifth of the amino acids in fibroin.

Stewart says his goal was to characterize the adhesive silk fiber "for the purpose of trying to copy it" so a synthetic version can be used as a surgical adhesive. he found the caddisfly silk is a fiber made of large proteins named fibroin (fye-bro-in) with an amino acid named serine making up a fifth of the amino acids in fibroin.

The silk is a continuous-filament fiber consisting of fibroin protein, secreted from two salivary glands in the head of each larva, and a gum called sericin, which cements the two filaments together.
