Some insect blood must be purple - the colour 'puce' is named after the French for 'flea' namely 'puce', because it's the colour that emerges when you squash a flea. Actually the blood of insects is white. For eg:The colour of blood of cockroache is white.
Bees and other insects don't have hearts in the way the higher animals do. They don't have blood, either, but do have a clear or yellowish fluid called hemolymph surrounding their tissues which carries nutrients around the body. The insects' movements tend to keep the hemolymph moving around their body.
Spiders have colorless blood. It is called hemolymph and transports nutrients, hormones, oxygen and cells. Spiders don't have blood, they have hemolymph. it is copper based not iron based. both of their main functions is to carry oxygen for respiration. copper rusts green, iron red.
Hemolymph.
Insect blood is generally either totally colourless or a very faint yellow or green colour.
because hemolymph does not carry oxygen
flies are commonly associated with garbage
ear drum
Hemolymph
nephridia
All bugs are considered insects. However, an inchworm does not have the traits associated with bugs it is part of the larger insect family.

fist of all it is known as an 'open' circulatory system.. that means the circulatory fluid (hemolymph) is not contained in vessels. insects have a dorsal vessel with a sort of heart (but is not like that of mammals). insects only transport nutrients and waste and NOT oxygen. for this reason, their circulatory fluid, hemoplymph, is greenish in colour. the cavity in which the hemolymph opens is known as the haemoceal. hemplymph passes into the haemoceal through openings called ostia (sing. ostium)
* Oxygenated hemolymph (blood), coming from ctenidia, flows into heart's atria, * then it flows into heart's ventricle, which pumps the hemolymph into arteries, * from arteries, hemolymph flows into the hemocoel; * then it's caught again inside veins and brought directly into afferent ctenidial vessels or into accessory branchial hearts, which pump it inside ctenidia again, for oxygenation. Hemolymph flows also into the pericardium, the celomatic membrane wich contains the systemic heart, and, from it, hemolymph reaches and flows into the excretory ducts.
