Why Is Insect Blood Green Or Yellow? You've probably heard someone use the phrase "blood red," but have you ever wondered if all blood really is red? For example, think about the bugs you've seen splatter against your car's windshield, leaving behind a clear, yellowish, or greenish liquid. That liquid, is hemolymph, or insect blood. Insect Blood
The blood of an insect functions differently than the blood of a human. In humans, blood gets its red color from hemoglobin, which travels through blood vessels carrying oxygen from the lungs to the rest of the body. Insect blood, however, does not carry gasses and has no hemoglobin. Instead, bugs have a system of tubes that transport gasses directly between their cells and the outside air. In fact, insects don't even have blood vessels. 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. 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. Pigment Pumping blood is a slow process: it takes about eight minutes for an insect's blood to circulate completely. Like human blood, bug blood carries nutrients and hormones to the insect's cells. The greenish or yellowish color of insect blood comes from the pigments of the plants the bug eats. indianapublicmedia.org/amomentofscience/green-as-blood.php

Blue blood: There are some creatures, however, for whom blue blood is the norm. Crustaceans, spiders, squid, octopuses, and some molluscs all have blue blood as a result of having a different respiratory pigment. Rather than haemoglobin, these creatures use a protein called haemocyanin to transport oxygen. The differing structure of the pigment, as well as the incorporation of copper atoms instead of iron, leads to the blood being colourless when deoxygenated, and blue when oxygenated. They also bind to oxygen in a different manner to haemoglobin, with two copper atoms binding to each oxygen molecule. io9.gizmodo.com/why-horseshoe-crabs-bleed-blue-and-worms-bleed-green-1652384102

We have a national dragonfly? What next? There is actually a greater variety of invertebrates compared to vertebrates. The green darner looks like the emperor dragonfly except for the former has green eyes and the latter has blue eyes. A female green darner is all green with an orange abdomen while the female emperor dragonfly is all green.
