What do mosquitoes eat? You’ve probably heard that mosquitoes eat blood, but did you know that they also eat flower nectar and fruit juices?

What do mosquitoes eat? You may be surprised

Some mosquitoes are specialized to sting only a specific group of animals, like birds or mammals. Other species are capable of attacking differing types of vertebrates.

Mosquitoes are flying insects that board most parts of the globe. These small invertebrates are considered a nuisance by society. As they have an inclination to sting and cause lesions that cause itching and inflammation. Despite this, the fact is that not all mosquitoes live this manner, but dine in other ways.

Formally, several species of Diptera are called “mosquitoes”. during this article. However, special emphasis are going to be placed on the Culicidae, which contains the best-known species. Keep reading and know what biting mosquitoes eat.

What do mosquitoes look like?

These invertebrates have atiny low body divided into 3 sections: head, thorax and abdomen. Additionally, the members of their group are characterized by having two defined wings, which is why they’re called Dipterae (di– two, pteros – wings). Additionally, they’re well adapted for flight, and have structures to provide them a particular stability.

The head region contains the eyes, antennae and mouth – different organs in each species. The thorax is that the area where all limbs are joined. For instance the three pairs of legs and also the 2 wings. Finally, the a part of the abdomen contains the genitals and includes a cylindrical and elongated appearance.

The mouth (proboscis) of those insects is elongated and might be presented in two different conformations: sucking and stinging-sucking. As you’ll be able to imagine, only those with the opposite kind of mouthparts are capable of stabbing and sucking blood. Something referred to as hematophagous feeding.

What do mosquitoes eat?

In general, most mosquitoes kill sugary substances and extremely few prey on blood. This is often because each individual mosquito is proscribed by the kind of mouthparts it’s and most of them don’t seem to be stingers. Thanks to this characteristic, these invertebrates will be divided into two groups with different diets:

Licking or sucking:

Mosquitoes with this kind of mouth are dedicated to digesting various foods like fruit, juice, nectar and most sugary substances. They use their long mouths to access these resources, which are sucked with great force. All male specimens have this sort of mouth structure (and so do females in some species).


As the name suggests, this sort of Diptera focuses. On stinging and sucking the blood of mammals (hematophagus) to get the nutrients necessary for replica.

Because the saliva secreted by mosquito bites contains some anticoagulants to form the blood flow. The skin of humans reacts allergically to that, causing swelling and itching. However, only the females of some species have this mouth structure.

Why do mosquitoes feed on blood?

The reason these insects take advantage of blood is that this fluid is that the main source of essential proteins for the event of their eggs. Precisely for this reason, only females are hematophagous, since they’re to blame for laying the eggs.

Generally speaking, they begin the assembly of the eggs after they need consumed blood. Therefore the females need plenty of nutrition if they shall lay an oversized number of eggs. With mosquitoes, the common female uses only about 2 to three milligrams of blood, which may help them incapacitate to 100 eggs.

How does the mosquito guide itself to bite?

All animals emit certain “smells” that are noticeable to other organisms, among which pheromones and allelochemicals are the foremost important. To guide themselves, bloodsucking insects use their antennae to detect these substances, which tell them the direction their victim is facing.

Specifically, mosquitoes are drawn to a mix of pheromones and other compounds like CO2, carboxylic acid, ammonium and estradiol. These substances are usually a product of normal human metabolism and frequently accumulate within the hands, feet, head and armpits.

For this reason, some people are more affected than others by mosquito bites because their bodies accumulate more of those substances. additionally, some species of those insects also tend to prefer certain kinds of blood, so blood chemistry also affects this process. Finally, the entire body seems to be a natural lure for these invertebrates.

What do mosquito larvae eat?

The larvae of this group may behave slightly differently, as their appearance and morphology differ from an adult. Because of this, the diet at this stage of the Diptera life cycle can be classified as follows:

Suspensivore (organic matter): This group includes most mosquito larvae, since most of them specialize in eating microorganisms or organic matter suspended in the water.

Predators: The larvae of some species often use their powerful mandibles to pursue and capture some larvae of other insects.

The danger behind their sting

Although they seem harmless, mosquito bites have great medical relevance in society. This is because they are responsible for transmitting various types of viruses, bacteria, protozoa and nematodes that cause various diseases in humans. For this reason, these insects are considered the most dangerous group in tropical areas.

Despite this, these organisms show one of the most interesting adaptations in the animal world: they take advantage of blood to obtain their nutrients. Furthermore, the mechanisms they use to recognize their victims are so sensitive that they perceive incredibly subtle signals. In this way, incredible complexity is observed even in animals as small as these.
