Figure 3

SEM images of (a) honeycomb-like structure of chitin extracted from H. illucens larvae (L), pupal exuviae (PE), with focus on adult chitin (A, Ai, Aii, Aiii). Bars in (L, PE, A):40 µm; bars in (Ai-iii): 5, 10 and 1 µm, respectively (b) Chitin from H. illucens larvae (L), pupal exuviae (PE) and dead adults (A) before (unbleached) and after (bleached) bleaching treatment Bars (L, PE, A): 1 and 500 µm. (c) Chitosan from H. illucens larvae (L), pupal exuviae (PE) and dead adults (A) before (unbleached) and after (bleached) bleaching treatment. Bars in (L): 1 µm; bars in (PE): 500 and 3 µm; bars in (A): 1, 40 and 500 µm.
