The mean content of each essential amino acid, in g/100 g of crude protein, in each species of edible insect, alongside the total sum of essential amino acids. As neither of the two published papers on C. butyrospermi's amino acid content reported tryptophan, the mean total essential amino acid contents have here been calculated in the absence of tryptophan. The horizontal lines superimposed onto each panel refer to current estimates for adult requirements of each amino acid, obtained from WHO/FAO/UNU (75). Within each amino acid panel, reported is, from left to right: Hermetia illucens (black soldier fly, BSF; in gray), Musca domestica (house fly, HSF; in purple), Rhynchophorus phoenicis (palm weevil, PL; in orange), Cirina butyrospermi (shea tree caterpillar, STC; in green), and Macrotermes bellicosus (termite, TM; in blue).
