The tiger beetle is a subfamily (the taxonomical level immediately below the family) of ground beetles. The larvae spend their entire lives hiding in burrows until reaching maturity. The adults, whose Identification comes easily from the metallic iridescent shell, are usually half an inch to an inch in size. Many species are poorly studied and some are endangered.
How long does it take for a tiger beetle to mature?
Once it hatches, the larva creates a burrow at the site where the eggs are laid. Through a long process of molting and growing, it can take one to four years for the larva to reach adulthood. The timing of maturity can vary. Some will wait out the winter and then mate in the spring. Others mate in the summer and then make the larvae wait out the winter. The adults only live a few months before perishing at the end of their lifespan.
How to identify a tiger beetle?
Identification can be a little difficult because they look so much like other beetles. One easy method of identification is to look at the shell. The rounded head and thorax, plus the elongated abdomen, are covered in metallic blue, green, red, or orange. These unique colors are created by pigments in the exoskeleton and then refracted by the exoskeleton’s unique surface. The wing covers on the abdomen also sometimes have marks or spots on them.

How do carabid beetles reproduce?
Carabid beetles employ a wide variety of ecological strategies, however some generalizations can be made to represent the majority of species. Carabid beetles exhibit complete metamorphosis. This means that the insect passes through four separate stages of growth: egg, larva, pupa, and adult. On average, carabid beetles produce one generation per year. After finding a suitable site, females will singly deposit between 30 and 600 oval eggs within the soil or in the layer of plant residues on the soil surface. Protected egg sites are very important because young larvae have limited mobility for finding food and their relatively soft bodies are vulnerable to predators. Parental care, including egg guarding and seed cacheing, has been observed in some species that produce small litters. Species are sometimes distinguished as either having winter or summer larvae. Larvae live entirely under the soil surface, where they pupate usually after three larval stages. Adults can live between one and four years. Larger species, as well as those that over-winter as larvae, tend to have the longest life spans (Lovei and Sunderland 1996). While many ground beetle species have functional wings, flight is used primarily for dispersal, such that they spend nearly their entire lives on the ground. Some have also been observed climbing plants in search of prey.
Why are carabid beetles sensitive to tillage?
Due to their relatively soft bodies, carabid beetle larvae are especially sensitive to tillage practices. Minimum tillage systems also preserve surface vegetation and mulch, which can provide microhabitats for ground and tiger beetles as well as protection from environmental conditions and other predators.
What is the indirect lethal effect of carabid beetles?
Indirect Lethal Effects. The carabid beetle feeds on a prey item that has been poisoned by the pesticide and consequently dies.
How do insecticides affect carabid beetles?
As a consequence, pest species normally controlled by carabid beetles can increase after application of some insecticides . One way to mitigate the effects of insecticides is to establish beetle banks (See section on habitat management/conservation practices). Beetle banks have been shown to provide a site for colonizing beetle populations while crops are treated with pesticides (Lee 2001). Furthermore, the results of one study suggests that reducing pesticide treatment to one quarter the normal application rate can lead to an increase in the overall abundance of carabid beetles (Navntoft et al., 2006).
What are carabid beetles?
Carabid beetles, an insect group containing ground and tiger beetles, are important biological control agents in agroecosystems. With their large eyes, spiny powerful legs, and large jaws, carabid beetles are formidable predators in the insect world. They live on the surface of the soil where they capture and consume a wide assortment of soil dwelling insects, including caterpillars, wireworms, maggots, ants, aphids and slugs. Several ground beetles will also eat the seeds of troublesome weeds and are considered one of the "many little hammers" that help regulate weed populations (Liebman and Gallandt 1997). Conserving ground beetles through habitat manipulations and cultural practices can enhance the natural regulation of arthropod pest and weed populations, reducing the need for chemical controls.
Habitat
- Some tiger beetle species can be found in trees, but the vast majority are ground-dwellers. Different species can be found along the seashore and in the sand dunes, in open expanses or paths in wooded forests, and upon clay banks in close proximity to lakes and rivers. They appea…
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.
Overview
Tiger beetles are a large group of beetles, from the Cicindelinae subfamily, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, Rivacindela hudsoni, can run at a speed of 9 km/h (5.6 mph; 2.5 m/s), or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Ori…
Taxonomy
Tiger beetles were traditionally classified as the family Cicindelidae but most authorities now treat them as the subfamily Cicindelinae of the Carabidae (ground beetles). The most recent classifications, however, have relegated them to a monophyletic subgroup within the subfamily Carabinae, though this is not yet universally accepted. Accordingly, there is no consensus classification for this group, at any level from family down to subspecies, and it can be exceedin…

While members of the genus Cicindela are usually diurnal and may be out on the hottest days, Tetracha, Omus, Amblycheila and Manticora are all nocturnal. Both Cicindela and Tetracha are often brightly color…
Adaptations
Tiger beetles display an unusual form of pursuit in which they alternatively sprint quickly toward their prey, then stop and visually reorient. This may be because while running, the beetle is moving too fast for its visual system to accurately process images. To avoid obstacles while running they hold their antennae rigidly and directly in front of them to mechanically sense their environment.
Fossil record
The oldest fossil tiger beetle yet found, Cretotetracha grandis, comes from the Yixian Formation in Inner Mongolia, China, and dates to the early Cretaceous Period, 125 million years ago. Most fossils found are grey or yellow silty mudstone. Traits that identify Cretotetracha as Cicindelinae include long mandibles shaped like sickles, simple teeth arranged along the mandible's inner surface, antennae that attach to the head between the base of the mandibles and the eye. The le…
