fat body
Quick Summary
The fat body is a fatty tissue found in nearly mature insect larvae that serves as a food reserve. It is an important organ for intermediary metabolism, storing fat, glycogen, and protein, especially during metamorphosis. These stored materials are released as needed by tissues for energy, growth, and reproduction. The fat body is bathed by hemolymph, which is the insect's circulatory fluid. Insects require various nutrients, including amino acids, fats, and carbohydrates, with specific needs varying by species. Some insects rely on symbiotic microorganisms within specialized cells to obtain essential vitamins.123
