Are There Any Species Of Large Insects That Feed On Tarantulas?


Tarantulas, with their large and intimidating appearance, are known for being formidable predators in the insect world. However, even these mighty creatures are not immune to predation. There are several species of large insects that have developed unique adaptations and strategies to overcome the challenges posed by tarantulas. In this article, we will explore the fascinating world of insects that feed on tarantulas and delve into their behaviors, hunting techniques, and predatory strategies.

Insects That Feed on Tarantulas

1. Ambush Bugs

1.1 Overview of Ambush Bugs

Ambush bugs belong to the family Reduviidae and are known for their remarkable camouflage and ambush hunting tactics. These insects have short, powerful forelegs that they use to grasp their prey. With their incredible agility and lightning-fast strikes, ambush bugs are capable of overpowering creatures much larger than themselves.

1.2 Ambush Bugs and Tarantulas

Ambush bugs are opportunistic predators and are known to prey on a wide variety of insects. While they primarily target smaller insects, there have been documented cases of ambush bugs successfully hunting and feeding on tarantulas. These encounters usually occur when the tarantula is vulnerable, such as during molting or mating.

1.3 Behavior and Adaptations

Ambush bugs rely on their exceptional camouflage to blend seamlessly into their surroundings, often resembling twigs or dried leaves. This tactic allows them to remain hidden from their prey until the opportune moment to strike. Additionally, their powerful forelegs and sharp beak enable them to deliver a potent venomous bite, immobilizing their prey within seconds.

2. Tarantula Hawks

2.1 Overview of Tarantula Hawks

Tarantula hawks are large, wasp-like insects that belong to the Pompilidae family. Despite their imposing size, they are not known to harm humans as they primarily feed on nectar. However, female tarantula hawks possess a unique and terrifying ability: they are solitary hunters that specifically target tarantulas as hosts for their offspring.

2.2 Tarantula Hawks and Tarantulas

Female tarantula hawks locate tarantulas by their pheromones or by visually scanning the area. Once a tarantula is found, the wasp engages in a confrontation, attempting to sting and paralyze the spider. The tarantula hawk then proceeds to lay an egg on the immobilized tarantula’s body, providing a fresh and living food source for its larva.

2.3 Hunting Behaviors

Tarantula hawks possess a formidable stinger that delivers an excruciatingly painful sting to their prey. The venom injected with the sting temporarily paralyzes the tarantula, allowing the wasp to successfully lay its egg without risking an attack from the spider. This strategic paralysis ensures a guaranteed and fresh food source for the developing larva.

3. Assassin Bugs

3.1 Overview of Assassin Bugs

Assassin bugs, classified under the family Reduviidae, are diverse in their feeding habits and can be found in various ecosystems worldwide. They are aptly named for their predatory nature, often lying in wait for unsuspecting prey and striking with precision.

3.2 Assassin Bugs and Tarantulas

While assassin bugs are not primarily known for preying on tarantulas, some species have been observed capturing and consuming these formidable spiders. The encounters between assassin bugs and tarantulas usually occur during the tarantulas’ vulnerable moments, such as when they are molting or in the midst of a mating ritual.

3.3 Feeding Strategies

Assassin bugs are skilled hunters and use a combination of stealth and their unique rostrum (a needle-like mouthpart) to inject venom and immobilize their prey. They then suck out the internal fluids of the tarantula, leaving behind an empty husk. This feeding strategy not only provides nourishment but also eliminates potential threats, ensuring a safer environment for the assassin bugs.

4. Giant Water Bugs

4.1 Overview of Giant Water Bugs

Giant water bugs, also known as electric light bugs or toe-biters, belong to the family Belostomatidae. As their name suggests, these insects are commonly found in aquatic habitats, such as ponds and streams. Despite their aquatic lifestyle, some species of giant water bugs are known to venture out of water to capture prey, including tarantulas.

4.2 Giant Water Bugs and Tarantulas

Giant water bugs possess powerful forelimbs adapted for capturing and immobilizing their prey. While they primarily target aquatic insects and small fish, there have been instances where these formidable bugs have been observed preying on tarantulas. These encounters usually happen when tarantulas inadvertently approach the water’s edge in search of food or mates.

4.3 Predatory Behavior

When encountering a tarantula, giant water bugs use their strong forelimbs to grab and secure the spider, ensuring it cannot escape. They then inject enzymes into the tarantula’s body to break down its tissues, making it easier to consume. This predation method ensures a sufficient food source for the giant water bug, allowing it to sustain itself in its aquatic habitat.

5. Robber Flies

5.1 Overview of Robber Flies

Robber flies, part of the Asilidae family, are predatory insects known for their exceptional agility and hunting skills. These flies are characterized by their robust bodies, large compound eyes, and a long, needle-like mouthpart with sharp cutting and sucking features.

5.2 Robber Flies and Tarantulas

While not a common occurrence, there have been reports of robber flies preying on tarantulas. These encounters usually involve smaller or vulnerable tarantula species that are unable to mount effective defenses against the agile and swift robber flies.

5.3 Hunting Techniques

Robber flies employ various hunting techniques when targeting tarantulas. They often rely on their exceptional eyesight and quick aerial maneuvers to surprise and catch their prey. Once captured, robber flies use their sharp mouthparts to immobilize the tarantula and extract its body fluids for sustenance.

6. Other Predatory Insects

6.1 Praying Mantises

Praying mantises are renowned for their predatory behavior and the distinctive stance they assume, resembling a praying position. While they primarily feed on smaller insects, larger mantis species have been observed hunting and consuming tarantulas. These encounters usually occur when the mantis successfully ambushed an unsuspecting tarantula.

6.2 Spiders

Despite tarantulas being skilled predators themselves, they are not entirely immune to being preyed upon by other spider species. Some smaller spider species, such as certain jumping spiders, have been observed capturing and feeding on tarantulas. These encounters may happen when the tarantula is vulnerable or unable to effectively defend itself.

6.3 Antlions

Antlions, though not insects (belonging to the family Myrmeleontidae), are included here due to their predatory nature. These fascinating creatures are known for their unique pit-trap hunting strategy. While antlions primarily target ants and other small insects, there have been instances where they have captured tarantulas that accidentally stumbled into their sand pits.

7. Predatory Strategies

7.1 Venomous Attacks

Many of the predatory insects mentioned in this article utilize venom to immobilize their prey, ensuring a successful kill and minimizing the risk of retaliation. The venom injected by these insects typically contains potent neurotoxins that rapidly paralyze their tarantula prey.

7.2 Ambush and Stealth

Several of the mentioned insects rely on their exceptional camouflage and stealth to ambush unsuspecting tarantulas. Their ability to blend into the environment allows them to get close to their prey unnoticed, increasing their chances of a successful hunt.

7.3 Leg Trapping

Some insects, such as assassin bugs and robber flies, have developed unique adaptations to capture tarantulas. They employ their strong forelimbs or sharp mouthparts to immobilize the spider’s legs, rendering it unable to escape. By disabling the tarantula’s primary means of defense, these insects can safely consume their prey.

Are There Any Species Of Large Insects That Feed On Tarantulas?


While tarantulas may be formidable predators in their own right, they are not exempt from being preyed upon by large insects. Ambush bugs, tarantula hawks, assassin bugs, giant water bugs, robber flies, and other predatory insects have evolved unique adaptations and hunting strategies to overcome the challenges posed by tarantulas. These predator-prey dynamics highlight the fascinating intricacies of the natural world and remind us of the coexistence and interdependence of different species.
