Generally, a tiger beetle locates its live prey visually and after that starts to pursue it in the course of active running interspersed with pause-and-look behaviour (Gilbert, 1987; Gilbert, 1997) or the beetle waits in a shaded area and attacks the prey when it is approaching (Kaulbars & Freitag, 1993).
How do Tiger Beetles kill their prey?
Next the tiger beetle freezes for a moment (stops), and starts to chase the prey fast in the case of beetles, or nobble the prey slowly in the case of slow caterpillars. The mandible attacks were conducted against three parts of the prey body: front, middle and back.
How does a Tiger catch its prey?
How does a tiger catch its prey? T igers can sprint at speed, but cannot chase fast prey like deer for long distances. Instead, they use cunning behaviour to get close enough to launch an attack. The tiger creeps slowly forward, keeping low to the ground and using its striped coat to camouflage it in the vegetation.
How are tiger beetles adapted to their environment?
Tiger beetles are extraordinary predators and masterfully adapted to their environment. Their common name refers to violence with which they tear prey apart while eating. This aggressive behavior is apparent in all life stages of the beetle. Larval tiger beetles burrow vertical pits in soft sand to await their next meal.
How do tiger beetles lay eggs?
After mating, female tiger beetles construct a burrow to lay their eggs. Females appear to prefer damp soil when depositing eggs. When the beetle larvae hatch they are capable of hunting on their own. Each larvae digs a tunnel, and captures any prey that wanders into range.
How do beetles catch their prey?
The hunting pattern for beetles was quite simple for both hunter species. The main attack sequence was straightforward: prey perception, turn, stop, chase, attack on the middle part of the body, releasing the prey, re-attack, eating the prey.
How do tiger beetles eat?
From its crouching perch, a tiger beetle waits for its prey. Their vision is acute and when a victim passes by, the tiger beetle lunges and grabs its target (like a tiger). The quarry is clenched between powerful sickle-like mandibles and devoured on the spot. The fast-moving adults will also run down their target.
Are tiger beetles carnivores?
Tiger beetles are carnivores as both adults and juveniles. The female tiger beetle lays her eggs singly on the ground. Upon hatching, the immature stage, called the larva, constructs an underground burrow.
What causes tiger beetle to go blind while chasing its prey?
Tiger beetles use this incredible speed to run down both prey and mates. But as they sprint, their environment becomes a blur because their eyes simply can't gather enough light to form an image.
How does the tiger beetle protect itself?
These long-legged beetles are fierce predators that use their formidable speed and large mandibles, or mouthparts, to hunt smaller insects and spiders. They often protect themselves with chemical defenses, and one species even releases a substance that smells like bubble gum.
Can a tiger beetle fly?
The six-spotted green tiger beetle is an active creature with the ability to run and fly at great speeds; this is not the case for most beetles. They can also render a painful bite to humans, so one must be careful not to make them feel threatened.
How does the adult tiger beetle locate its prey?
Tiger Beetles fly so fast while chasing prey that they temporarily go blind! Tiger Beetles communicate in ultrasound, which sounds like a “click”. It is said that it helps them detect predators like bats which also use ultrasounds to hunt insects.

How fast do tiger beetles fly?
1.2 mph"The top speed for my tiger beetles is 0.5387 meters per second (1.2 mph)," said Gilbert. "This is not very impressive, but the beetles are a lot smaller than Michael Johnson. If we scale the speed for body length, we get a much different picture."
Why do tiger beetles stop and go?
The answer is that the insect's ability to see shuts down after it accelerates toward prey .
How fast can a tiger beetle run?
Johnson, the world-record holder, can run 200 meters in 19.32 seconds, which averages to a speed of 10.35 meters per second (or 23.1 mph.) "The top speed for my tiger beetles is 0.5387 meters per second (1.2 mph)," said Gilbert. "This is not very impressive, but the beetles are a lot smaller than Michael Johnson.
How many times does a tiger beetle stop?
In nature, such stop-and-go chase patterns are unusual, but the tiger beetle is unique. In the midst of hot pursuit, it stops three or four times to reorient itself toward the prey. Even after a few stops, the tiger beetle has enough time to overtake its prey during its high-speed pursuit.
What is the largest beetle in New York?
The largest variety in size in New York state is Cicindela formosa. One variety of tiger beetle, Cicindela puritana, which might soon find itself on the endangered species list, lives along the banks of the Connecticut River throughout New Hampshire, Vermont, Massachusetts and Connecticut.
What is the behavior of a tiger beetle?
Behavior of the Tiger Beetle. Tiger beetles spend the vast majority of their time hunting for prey. They are solitary animals, and only interact with other tiger beetles when breeding.
How do tiger beetles reproduce?
Reproduction of the Tiger Beetle. After mating, female tiger beetles construct a burrow to lay their eggs. Females appear to prefer damp soil when depositing eggs. When the beetle larvae hatch they are capable of hunting on their own. Each larvae digs a tunnel, and captures any prey that wanders into range.
How many species of tiger beetles are there?
The 2,600 species of tiger beetle can be found in virtually any color. All tiger beetles have six long legs, a pair of antenna, and long mandibles. These mandibles are similar to jaws, and are used for disabling their prey and biting potential predators.
How did the tiger beetle get its name?
Tiger Beetle. Tiger beetles get their name from their voracious predatory habits. They are the “tiger” of beetles, if you will. Both larvae and adult tiger beetles strike fear into the hearts of other insects. This group of beetles comes in a variety of shapes and colors. Read on to learn about the tiger beetle.
What is the fastest insect on a plane?
In fact, an Australian species ( Cicindela hudsoni) holds the record for fastest insect on the plane.t! This species can run 5.6 mph, which is 125 times its body length per second. Spittin’ Fire – In addition to their massive mandibles, used to dismember their prey, tiger beetles have an additional secret weapon.
What are some interesting facts about tiger beetles?
Interesting Facts About the Tiger Beetle. When picturing a beetle, you typically don’t think of a vicious predator. Tiger beetles have a number of interesting traits that they use for survival. Baby Killers – The larvae of tiger beetles are just as competent hunters as the adults. No cute, helpless, babies for this group of beetles!
Do tigers need a heat source?
They can be provided with plants, and should be fed a diet of crickets and other insects. Your beetles should be provided with a heat source, and the desired temperature varies based on the beetle species.
Abstract and Figures
Abstract: When a beetle chases its prey, what laws does it follow, if any? Theoretically, there are multiples strategies that a beetle could use to intercept its prey. By analyzing the pursuit dynamics of Tiger beetles, we found that the beetle adjusts its orientation to minimize the angle between its heading and the prey.

Why do tiger beetles burrow in sand?
Larval tiger beetles burrow vertical pits in soft sand to await their next meal. When an unlucky insect wanders by, powerful mandibles explode from beneath the ground, seizing their victim before dragging them into the pit to be torn apart.
Why do tiger beetles swivel their antennae?
Many insects swivel their antennae around to get extra sensory data for navigating their environments. But tiger beetles rigidly hold their antennae forward and just off the ground, allowing them to sense and react to any obstruction while keeping their eyes on their quarry.
What is the name of the beetle that burrows in soft sand?
This aggressive behavior is apparent in all life stages of the beetle. Larval tiger beetles burrow vertical pits in soft sand to await their next meal.
Do tiger beetles blind themselves?
Curiously, tiger beetles run so fast, they effectively blind themselves! As they run at full speed, not enough light particles (photons) are received by their eyes. This lack of light degrades a beetle’s sight over time. So frequent stops mid-pursuit are necessary for successful hunting (2).
Do tiger beetles outpace their prey?
Even with stopping, tiger beetles still easily outpace their running prey. While the beetles may have excellent sight for prey, they rely on the sensation of their antennae for avoiding obstacles (3). Many insects swivel their antennae around to get extra sensory data for navigating their environments.
Appearance
Habitat
Geographic range
- Tiger beetle species can be found across virtually the entire planet, with only a few exceptions. The only locations entirely without tiger beetles are Tasmania, Hawaii, Antarctica, and the Maldives.
Diet
- These voracious predators will eat virtually anything that they can catch. They are, however, relatively small so the usual victims are smaller insects. The size of prey typically depends on the species of tiger beetle; animals with large mandibles can feed on larger insects, while those with smaller mandibles feed on smaller ones.
Conservation
- Tiger beetles are threatened by human interaction, but the type of threat usually depends on the species and its habitat. Human interaction with tiger beetles is mainly indirect. Pollution, habitat destruction, and land development are the main threats to tiger beetles. Tiger beetles can and will bite when handled, the pain inflicted varies by the mandible size.
Prevention
- Tiger beetles can be easy to care for, but always ensure the species you plan on keeping is legal in your location. Dont expect the tiger beetle to be a cuddly pet, frequent handling should be avoided.
Behavior
- Tiger beetles spend the vast majority of their time hunting for prey. They are solitary animals, and only interact with other tiger beetles when breeding. When a male beetle breeds, he will stay with the female for a short amount of time to chase off other males, this is called mate guarding.
Reproduction
- After mating, female tiger beetles construct a burrow to lay their eggs. Females appear to prefer damp soil when depositing eggs. When the beetle larvae hatch they are capable of hunting on their own. Each larvae digs a tunnel, and captures any prey that wanders into range.
