What Is a Tiger Beetle?

A tiger beetle is an insect approximately 0.5 inch (1.25 cm) long with wings, long legs, and long antennae. It is estimated that there are more than 1,500 species of tiger beetle throughout the world, with the greatest number living in warm, tropical climates. These different species encompass a wide range of colors. The most common colors seen are brownish gray and black, colors designed to blend in with the environment, while some species sport brilliant hues of iridescent copper, green, or blue.

Tiger beetles are predators, feeding on small spiders, insects, worms, and snails. They can run and fly rapidly, and are able to catch prey both on the ground and while airborne. Their speed makes tiger beetles difficult for humans to catch, but they are prey to dragonflies, spiders, lizards, and toads. Tiger beetle larvae are also aggressive predators, digging holes into which they pull unsuspecting prey which they devour with their powerful jaws.

Its overlapping, sickle-shaped mandibles give the tiger beetle a ferocious appearance. A tiger beetle doesn’t bite humans, though, unless it is handled. Both adult and larval tiger beetles are considered beneficial due to the wide variety of insects they eat. Most are active during the day, but a few species are nocturnal. Some species of tiger beetle are able to produce an odor in an attempt to deter predators.

After mating, the male remains with the female for a short time and protects her from other males. In June or July, female tiger beetles dig holes and lay one egg in each hole. After hatching, the larvae enlarge the holes and live inside, waiting for prey to crawl by. Tiger beetles emerge from these holes after they mature into the adult stage.

These insects are more active on sunny days. Their level of activity is determined by the amount of light, level of humidity, and air temperature. They go deep into their underground burrows during seasons with cold temperatures. Tiger beetles are an indicator species, which means that their presence is an indication of a healthy ecosystem, spoiled by few contaminants.

Around 100 species of tiger beetle are found in the United States. One common species is the six-spotted tiger beetle. This beetle sports a metallic green head, legs, antennae, and wing covers, known as elytra, and generally has six white spots on the wing covers. There are variations, though, with some six-spotted beetles displaying blue coloration, some displaying a different number of spots than six, and some possessing a solid color with no spots.

Frequently Asked Questions

What is a tiger beetle and how can it be identified?

Tiger beetles are a group of fast-moving, predatory insects known for their striking colors and aggressive hunting behavior. They can be identified by their elongated bodies, large eyes, and long legs designed for speed. Many species have iridescent or metallic bodies, with patterns that can include spots or stripes reminiscent of their namesake, the tiger.

Where do tiger beetles typically live?

Tiger beetles inhabit a variety of environments across the world, from tropical forests to temperate beaches. They prefer sunny locations with sandy or clay soils where they can effectively hunt and run. According to the Entomological Society of America, these beetles are often found in open habitats such as along paths, riverbanks, and coastal dunes.

What do tiger beetles eat?

Tiger beetles are carnivorous and primarily feed on other small insects and arthropods. Their diet includes ants, spiders, caterpillars, and many other invertebrates. They are known for their exceptional speed and agility, which allows them to chase down prey with remarkable efficiency. Their strong mandibles are adept at catching and crushing their meals.

How fast can a tiger beetle run and why are they so fast?

Tiger beetles are among the fastest insects on land. Some species can run at speeds of up to 5.6 miles per hour, which is equivalent to a human running at 480 miles per hour, relative to body size. This incredible speed is an adaptation for hunting; it allows them to rapidly close in on prey and escape from predators.

Are tiger beetles endangered?

The conservation status of tiger beetles varies by species. Some are common and widespread, while others are rare and endangered. Habitat destruction and pollution are significant threats to certain species. For instance, the Salt Creek tiger beetle is critically endangered, with conservation efforts in place to protect its remaining habitat in the United States.

How do tiger beetles reproduce and what is their lifecycle like?

Tiger beetles undergo complete metamorphosis with four life stages: egg, larva, pupa, and adult. After mating, females lay eggs in the soil. Larvae emerge as fierce predators, dwelling in burrows and ambushing passing prey. They eventually pupate in the burrow before emerging as adults, ready to continue the cycle. This lifecycle can span one to several years depending on the species and climate.
