Do Male Mosquitoes Drink Blood? Let’s Settle the Score.

When we think of mosquitoes, we often think of the pesky insect that bites and feeds on our blood. However, not all mosquitoes drink blood. In fact, only female mosquitoes feed on blood. This raises the question – do male mosquitoes drink blood? In this article, we will explore this topic to settle the score once and for all.

Do Male Mosquitoes Bite?

The short answer is no, male mosquitoes do not bite. Male mosquitoes primarily feed on plant nectar and other sugary substances. Their long mouthpart, known as a proboscis, is not designed to pierce skin and extract blood like that of female mosquitoes.

Furthermore, male mosquitoes do not require blood to reproduce, unlike female mosquitoes. Female mosquitoes require blood to obtain the necessary proteins to develop their eggs.

But Why Do Male Mosquitoes Exist?

It may seem like male mosquitoes do not serve any purpose, but that is far from the truth. Male mosquitoes play a vital role in the reproduction process. Without males, there would be no fertilization of eggs and no new mosquitoes to continue the life cycle.

Additionally, male mosquitoes are often responsible for pollinating flowers as they feed on nectar. This process is crucial for the survival of many plant species.

Which Mosquito Species Bite?

While male mosquitoes do not bite, not all female mosquitoes do either. Only certain species of female mosquitoes feed on blood. According to the Centers for Disease Control and Prevention (CDC), there are over 3,500 species of mosquitoes worldwide. However, only a small fraction of these species feed on blood.

Why Do Female Mosquitoes Bite?

As mentioned earlier, female mosquitoes require blood to develop their eggs. Female mosquitoes are equipped with specialized mouthparts to actively seek out blood sources. They are attracted to carbon dioxide, heat, and certain odors that are emitted by mammals.

Once a female mosquito has obtained a blood meal, she will digest the necessary proteins and nutrients to develop her eggs.

Do Mosquitoes Prefer Certain Blood Types?

It is a common belief that mosquitoes prefer to bite individuals with certain blood types. However, the scientific evidence for this is limited.

A study conducted by researchers at the University of Florida found that mosquitoes are more attracted to individuals who are type O blood than those with other blood types. However, the study only used volunteers with type O blood, so further research is needed to confirm these findings.

What Other Factors Attract Mosquitoes?

In addition to blood type, other factors can make individuals more attractive to mosquitoes. Dark-colored clothing, sweat, and certain scents can all draw mosquitoes in. Additionally, mosquito activity is often higher during the early morning and late afternoon hours.

Can Mosquitoes Transmit Diseases?

Unfortunately, mosquitoes are known to transmit a variety of diseases. Some of the most well-known diseases transmitted by mosquitoes include malaria, Zika virus, and West Nile virus.

When a mosquito feeds on an infected individual, the virus or parasite is ingested along with the blood meal. The virus or parasite then infects the mosquito’s salivary glands, allowing it to be transmitted to the next individual the mosquito bites.

How Can We Protect Ourselves from Mosquitoes?

  • Cover up with long sleeves and pants
  • Apply insect repellent containing DEET or picaridin
  • Use mosquito nets while sleeping
  • Eliminate standing water around the home, where mosquitoes typically lay their eggs


In conclusion, male mosquitoes do not drink blood, and only certain species of female mosquitoes feed on blood. While it may be frustrating to be bitten by mosquitoes, it is important to remember that they play a vital role in the ecosystem. By taking precautions to protect ourselves from mosquito bites, we can minimize the risk of contracting a mosquito-borne illness.
