In mosquitoes, hemocytes are functionally divided into three populations: granulocytes, oenocytoids and prohemocytes. [2] Granulocytes are the most abundant cell type. They rapidly attach to foreign surfaces and readily engage in phagocytosis. Oenocytoids do not readily spread on foreign surfaces and are the major producers of phenoloxidase ...
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).

Many insects, such as grasshoppers and bees, which actively pump the air sacs in their abdomen, are able to control the flow of air through their body. In some aquatic insects, the tracheae exchange gas through the body wall directly, in the form of a gill , or function essentially as normal, via a plastron .
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 ...
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
What does it mean to dream of a specific snake species, like a constrictor or rattle snake? If a very specific type of snake shows up in your dream, you can take that as a sign to research that ...
(Insects are one of the most diverse groups of organisms on Earth. They play important roles in ecosystems, including pollination, natural enemies, saprophytes, and biological information transfer.) One of the major works to be published in the area of zoology was Conrad Gessner 's Historia animalium , which was published in numerous editions ...
