Instead there is a hollow space inside their external skeleton in which their blood oozes around. This cavity extends to the antennas, legs, and wing veins, and makes a big mess when squashed. The bug's heart, a long tube that stretches the length of its body, pushes the blood from the rear end of the insect on forward. The bug may also have little hearts at the ends of its extremities to help move the blood along. And pumping blood is a slow process: it takes about eight minutes for an insect's blood to circulate completely.

Is it the Haemoglobin Molecule that is red, or is it the Iron associated with it that makes it red...?
Same question with the Insect blood... Is it the molecule itself, or another contributing factor?
fromThe protein is composed of two alpha chains (yellow) and two beta chains (red). Each chain binds a haem group (cyan) which is responsible for binding a molecule of oxygen. The iron atom which binds oxygen is shown as an orange sphere. A fully-loaded haemoglobin molecule binds four oxygen molecules.
The purpose of blood and insect colors varies depending on the species. Insects may use their colors to attract mates, camouflage themselves, or warn predators of their toxicity. Blood colors, on the other hand, serve as a way for organisms to transport oxygen and nutrients throughout the body.
The coloration of insects is often linked to their survival strategies. Bright colors may be used as a warning to predators, while dull colors can serve as camouflage. Some insects may also change their colors throughout their life cycle, adapting to their environment and needs.
The evolution of coloration in blood and insects is influenced by various factors such as environmental pressures, mate selection, and genetics. Natural selection plays a significant role in determining which colors are most advantageous for survival and reproduction.
Blood color can be an indicator of an organism's health. In humans, a bright red color indicates a healthy level of oxygen, while a darker color may suggest anemia or other health issues. In insects, the color of their blood can also change based on their health status, such as when they are infected with a parasite or disease.
Scientists use various methods to study blood and insect colors, including observing color patterns in the wild, conducting experiments in controlled environments, and analyzing genetic data. They may also use specialized techniques such as spectrophotometry and chromatography to measure and analyze the pigments present in blood and insect colors.
