Minimal digestion time is 35 min in fully active animals, but can last as long as 70 min in animals at rest after feeding. There is a high rate of enzymatic activity. (Neuweiler, 2000) Chew food into very tiny pieces, thus exposing more digestible soft parts to the digestive process. Chitin is resistant to the typical digestive system, resulting in parts of legs, antenna and wings passing through the tract fully intact.
