THE DIGESTIVE SYSTEM OF A BUTTERFLY
- Butterflies feed exclusively on liquids which may include nectar, dissolved pollen, mineralized water, urine, sweat, bodily fluids from decomposing animal corpses.
- After the food enters the digestive tract, enzymes extract proteins and minerals from the food.
- After digestion and extraction of proteins and other minerals the waste matter is expelled from the anus either in liquid form, or as tiny faecal pellets.
