Do spiders eat mosquitoes?

Introduction:

Spiders and mosquitoes are two of the most common insects found in households and gardens worldwide. While most people are familiar with the pesky nature of mosquitoes, only a few know about the feeding habits of spiders. One question that often arises is whether spiders eat mosquitoes or not. The answer to this question is not as straightforward as one might think. 

In this blog post, we will explore the relationship between spiders and mosquitoes and try to answer the question once and for all. We will look at the different types of spiders that prey on mosquitoes, their hunting techniques, and the benefits of having spiders in your home or garden. So, if you’re curious whether spiders eat mosquitoes, read on to find out!

What Spiders Eat:

  • Spiders are predators that feed on a variety of insects and other arthropods.
  • The diet of a spider can vary depending on its species and habitat, but most spiders are opportunistic feeders and will eat whatever prey is available to them.
  • Some common types of prey for spiders include flies, mosquitoes, moths, beetles, grasshoppers, and other spiders.
  • Larger spiders are also known to prey on small vertebrates such as lizards and frogs, and some species of spider have been known to eat other spiders of their species.
  • Most spiders use venom to immobilize their prey before feeding on it.
  • Spiders can digest their food externally by injecting digestive enzymes into their prey and then sucking out the liquefied remains.
  • Some species of spider are able to go for extended periods of time without food, and may even resort to cannibalism in times of scarcity.
  • While spiders are generally considered beneficial predators in the ecosystem, there are some species that can be harmful to humans and other animals, and precautions should be taken to avoid bites from venomous spiders.

Do spiders eat mosquito?

Yes, some species of spiders do eat mosquitoes. However, not all spiders feed on mosquitoes and some may prefer other types of prey. Spiders that are known to eat mosquitoes include jumping spiders, orb-weaver spiders, and wolf spiders, among others.

Type of mosquito-eating spiders:

There are many types of spiders that eat mosquitoes. Some of them are described below.

  1. Evarcha culicivora 
  2. Paracyrba wanlessi
  3. Rabidosa rabida

Evarcha culicivora

Common name: 

The common name of Evarcha culicivora is the “vampire spider.”

Distribution:

Evarcha culicivora is found exclusively in East Africa, specifically in Tanzania and neighboring countries. It is primarily found in savannah and forested areas, where its preferred prey, female mosquitoes that have consumed blood meals, are abundant. The spider’s distribution in East Africa is believed to be limited to certain areas due to its highly specialized feeding behavior. While the species has not been reported outside of East Africa, its discovery has sparked interest in the potential presence of other mosquito-specialist spiders in other parts of the world.

Characteristics:

Evarcha culicivora is a species of jumping spider with several unique characteristics:

Feeding behavior:

Evarcha culicivora preys exclusively on female mosquitoes that have consumed blood meals, making it a specialist in mosquito hunting. This behavior is believed to have evolved due to the increased availability of blood meals in the spider’s habitat.

Appearance: 

The spider has a distinctive black-and-white pattern on its body, with females being larger than males. It is a small spider, measuring between 4 to 5 millimeters in length.

Jumping ability: 

The spider’s jumping ability is its primary means of catching prey. It is known to stalk mosquitoes until it has the opportunity to pounce on them.

Sense of smell: 

Evarcha culicivora is able to detect the scent of a mosquito’s blood meal from a distance and can differentiate between blood-fed and non-blood-fed mosquitoes.

Habitat: 

The spider is primarily found in savannah and forested areas of East Africa, where its preferred prey, female mosquitoes, are abundant.

Evarcha culicivora  as mosquito eater:

Evarcha culicivora is a highly specialized spider that preys exclusively on female mosquitoes that have consumed blood meals, making it a mosquito eater. This unique feeding behavior has attracted the attention of scientists studying mosquito-borne diseases such as malaria, as the spider’s ability to prey on mosquitoes could potentially be used as a natural form of mosquito control.

Female mosquitoes are the primary vector for transmitting malaria to humans, and Evarcha culicivora’s preference for blood-fed female mosquitoes is believed to be due to the higher nutritional value of their blood meals, as well as the increased visibility of the mosquitoes due to their engorged abdomens. Studies have shown that the spider is able to detect the scent of a mosquito’s blood meal from a distance and can differentiate between blood-fed and non-blood-fed mosquitoes.

Paracyrba wanlessi

Common name: 

Paracyrba wanlessi is commonly known as Wanless’s spider.

Distribution:

Paracyrba wanlessi is a species of jumping spider that is found in Central and West Africa. Its distribution ranges from Cameroon to Ghana, with some reports of the species being found in Nigeria as well. Within this range, the spider is typically found in rainforest habitats, although it has also been reported in secondary forests and other wooded areas. While the spider’s range is relatively restricted, it is not currently considered to be threatened or endangered.

Size: 

The spider is relatively small, measuring between 4 to 5 millimeters in length.

Appearance: 

The spider has a distinctive black-and-white pattern on its body. The females are larger and more robust than the males.

Behavior: 

Paracyrba wanlessi is an active hunter, using its excellent vision and jumping ability to catch its prey. It is a diurnal spider, meaning it is active during the day.

Habitat: 

The spider is typically found in rainforest habitats, although it has also been reported in secondary forests and other wooded areas.

Diet: 

Paracyrba wanlessi is a generalist feeder, meaning it preys on a variety of small insects and other arthropods. Its diet includes flies, beetles, and other spiders.

Mating behavior: 

The males of this species have a unique courtship display that involves waving their front legs and vibrating their bodies. If the female is receptive, the male will approach and mate with her.

Paracyrba wanlessi as a mosquito eater:

Paracyrba wanlessi may indeed feed on mosquitoes. This spider has been observed hunting both adult and larval-stage mosquitoes in the bamboo forests of Malaysia. The spider’s hunting behavior is described as being “like a miniature cat,” as it stalks its prey before pouncing and capturing it. The study also found that the spider preys on mosquitoes regardless of whether the prey is empty or full.

While Paracyrba wanlessi is not considered a specialized mosquito eater or a natural form of mosquito control, recent evidence suggests that this spider may play a role in controlling mosquito populations in some areas. 

Rabidosa rabida

Common name: 

Rabid Wolf spider is the common name of Rabidosa rabida.

Distribution: 

Rabidosa rabida is a species of wolf spider found in North America. Its range extends from the southern United States, including Florida, Texas, and Arizona, to Mexico and parts of Central America.
