In most insects the midgut is the principal site of digestion and absorption, and the source of digestive (Fig. 50) enzymes. Anatomically, the midgut commences after the proventriculus and terminates at the ileum and juncture of the Malpighian tubules.
Generalized insect alimentary system (adapted from Chapman, The insects: structure and function).
