Hemocytes are phagocytes of invertebrates. Hemocytes in Drosophila melanogaster can be divided into two categories: embryonic and larval. Embryonic hemocytes are derived from head mesoderm and enter the hemolymph as circulating cells. Larval hemocytes, on the other hand, are responsible for tissue remodeling during development.
It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (for example, arachnids, crustaceans and insects).

The insect however has immune responses that fight against these parasites in order to defend themselves from infection. Hemocytes are the cells within the immune response that are able to detect the entry of a pathogen and initiate the immune response to kill the foreign particles within the insect.
[147] [150] Several groups of insects can be considered as either micropredators or external parasites; [151] [152] for example, many hemipteran bugs have piercing and sucking mouthparts, adapted for feeding on plant sap, [153] [154] while species in groups such as fleas, lice, and mosquitoes are hematophagous, feeding on the blood of animals.
Some invertebrates, including various insects, crabs, and worms utilize a modified form of the complement response known as the prophenoloxidase (proPO) system. [ 34 ] Antimicrobial peptides are an evolutionarily conserved component of the innate immune response found among all classes of life and represent the main form of invertebrate ...

An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
