∙ 11y agoInsect blood is not used to carry oxygen around their bodies like how it does in a human. While it can help carry it, it mostly transports nutrients and waste. As they lack red blood cells, their blood can appear colourless, white, pale yellow, or even green.
A mosquito is no different but people can mistake it for having red blood because it feeds on red blood and has it stored inside its body for digestion.

Can a cockroach have blue blood?
Cockroaches have blood, and are COLD-blooded creatures. Cockroach blood is not red because they do not use hemoglobin to carry oxygen. In fact their bloodstream is not used to carry oxygen either. They use a system of pipes called tracheae to bring the oxygen and remove carbon dioxide from their tissues. As a result other factors determine the blood color. Male cockroaches have relatively colorless blood. Larval females have colorless blood. Only adult females which are producing eggs have a slightly orange blood because of the protein vitellogenin which is made in the cockroach liver (its fat body) and transported through the blood to the ovary. This protein like chicken yolk is orange because it carries a carotenoid, which is a vitamin A like molecule needed by embryos to develop normally.
