"Since chitin is present only in the insect’s exocuticle, the chitin content of insects is likely not high."
"While “harder bodied” insects like adult beetles contained higher levels of ADF than softer bodied insects like Yellow mealworm larvae, silkworm larvae or cricket nymphs, those fiber levels were a result of higher levels of amino acids in the ADF fraction (Finke 2007). This suggests that insects with “harder” cuticles do not necessarily contain more chitin than softer bodied insects but rather contain higher levels of cross-linking proteins that are essential for sclerotization".
