People’s initial thought when they see a cockroach is to crush it. If that’s the case, you might expect to see red blood seeping from it but what you see is a distinct whitish, yellowish, or clear-colored fluid will develop surrounding the deceased cockroach. That’s because cockroaches have blood, but not the crimson kind that most species do.
Yes, cockroaches have blood. Their blood is not blue, red, green, black, or white. It is colorless, pale, creamy, orange, or yellowish blood is seen in cockroaches. This is determined by the cockroach’s sex and developmental stage. Because cockroaches lack hemoglobin, their blood is never crimson. They have hemolymph instead, which gives their blood a distinct tint.
Do cockroaches have blood? As seen above, cockroaches have blood, but, colorless and differ based on sex.
In this article, we will discuss what color of blood cockroaches have, what does cockroaches’ blood looks like, do all roaches have blood? and so on. Also, you will have an in-depth fact of the blood of cockroaches.
So, let’s dive in.
What Color Blood Do Cockroaches Have?
The blood of cockroaches is almost usually colorless. However, you may come across roaches with different blood hues ranging from yellowish to orange. The fundamental reason that hemolymph is not red is a lack of hemoglobin. But wait, there’s more. The hue of the cockroach’s blood is also determined by its sex.
Cockroach blood is transparent and colorless in both male and female cockroaches. However, in egg-laying females, the hue may change to yellowish or orange. This is because adult females go through hormonal changes as they begin to make eggs.
This causes the cockroach’s liver to produce vitellogenin, a protein. This is yellowish to orange in color. When a cockroach’s blood binds with vitellogenin, it turns orange or yellow. The blood will remain orange until the egg-laying process is completed.
What Does Cockroach Blood Look Like?
Cockroach blood appears to be identical to that of other insects with hemolymph. Depending on the kind and sex of the cockroach, it is transparent, whitish, or yellowish. Cockroach blood is not crimson because of a lack of hemoglobin. This is an iron-rich respiratory protein that contributes to the red hue of human blood.
Similarly, it does not flow in the same way that human or animal blood does. Hemolymph should not be expected to seep out like vertebral blood. Water, ions, carbohydrates, amino acids, and lipids make up its composition. As a result, it’s rather thick and creamy, like pus, with a very low viscosity.

Do All Roaches Have Blood?
Cockroaches all have blood (hemolymph). This aids in the transfer of materials, the delivery of important nutrients, and the removal of poisons in all cockroach species. Cockroaches cannot survive without hemolymph because their tissues and cells will not work properly.
Nonetheless, cockroach blood is not crimson, as it is in humans and vertebrate animals. Hemolymph is mostly colorless, however, it can be yellow or orange depending on the cockroach’s developmental stage. Some cockroaches have a whitish look and appear to be lifeless.
This does not, however, imply that they are devoid of blood. White cockroaches are the consequence of molting, and it may take several hours to a few days for the cockroach to build a new skin with its usual dark, brown color.
Do Baby Roaches Have Blood?
Baby cockroaches, like adult cockroaches, have blood. Cockroach nymphs have a higher hemolymph-to-body volume ratio than adult roaches. They require it to aid in their growth and development.
As previously stated, hemolymph serves a variety of purposes, including serving as a reservoir for water and other essential minerals. To survive their early days, baby roaches need as much water as possible. Body tissues can also use hemolymph to restore moisture lost during desiccation.
Hemolymph contains hemocytes, which are responsible for strengthening immunity throughout the formative days of a nymph. The baby roach is protected from pathogenic germs by its hemocytes. They also aid in the creation of new cells.
