A tiger is Coleoptera (coleoptera) tiger beetles (cicindelidae) insects collectively, for the medium-sized beetles, generally have bright colors and Banlan stain. Large head, front-mouth, palate big, so cross. A tiger is a carnivorous insect, daytime activities, often feeding insects on the road, when people close, often flying a short distance ahead, so there is the common name stumbling block, lead the way insects said. Common types are China tiger A multi-level type of tiger.
Body narrow, medium size; body often with metallic luster; big head, prominent compound eyes; lip base is broad-based than the antennae; filamentous antennae, 11; elytra long, cover the entire abdomen; abdomen visible six female and male 7, tarsus 1-3 forefoot with hair, can be distinguished from females. Undergraduate larvae lanes "s" shape, head and chest big, strong ossification, powerful palate, 5th abdominal section has a back with a hook projections feet long and sharp, suitable for digging.

Biology Description
Adults, larvae are predators, prey on other insects or small animals, which are often used in the biological control of insect predators predatory. Most species live on the ground, there are a few arboreal. Terrestrial species and more vivid in color, often metallic luster, elytra often with gold stripes or spots, usually appear on the road or the river beach. The most active in the sun, and sometimes stop in the road for a short distance or low-flying, flying quickly. Arboreal species, such as a genus of arboreal tiger tiger armor and wingless species, often in the coffee or tea tree twigs drill holes to lay eggs, become pests of economic crops in the tropics, but the larvae prey on scale insects, but also be beneficial . Bachelor of insects in the tropics one generation a year, in cold regions may be extended to 2-3 years of generation. Eggs in the soil, scattered production, spawning females before digging in the ground, each pit one egg. Larvae volts hole, the length and depth of the hole because of the extent of the hard soil varies: in hard soil, the hole slightly longer than the larvae of parasites; in the soft soil, the hole up to 1 meter deep. General larvae overwinter. Mature larvae pupate in the soil cavity, pupate before the first Xuekou closed, resulting in pupal chamber, a few species overwinter as adult. Arboreal species spawning females to wear a tube hole in the bark, deep into the pith, grain output of eggs, the female is about to be closed hole, the hole when larval development increases.

Classification and Distribution
Bachelor more than 2,000 species are known worldwide, our 1930 horn documented 101 species, distributed in seven genera, a tiger is cicindela most of 76 species. More than 120 species are known, a common Chinese tiger armor cicindela chinensis degeer, widely distributed nationwide; Kim 斑虎 A cicindela aurulenta f distributed in Jiangsu, Zhejiang and other southern China, foreign distribution in India, Myanmar, Nepal, Sikkim, etc. ground. Undergraduate classification generally used Horn (1926) system that, according to the concave shape of narrow or wide flat side of the chest piece, divided into two categories: narrow and wide plate plate Tiger Tiger CPI CPI, narrow plate tiger Group A includes two family four genera, are important and there is a lack of arboreal winged tiger A tiger A genus (tricondyla), were distributed in tropical or subtropical regions. Tiger CPI wide plate 29 genera, including 3 family, a family in which the tiger is a tiger is the largest genus of undergraduate, about half of the undergraduate species, widely distributed throughout the world. Tiger beetles currently have advocated as a subfamily of beetles step, and some of the tiger beetles into a lean tiger and tiger A subfamily subfamily alocosternalinae platysternalinae, but because according to the length and width of the chest, side panels, etc. Most scholars generally not used, just treat it as a class.

虎甲的幼虫
Most soil-dwelling tiger beetle larvae, a few types of arboreal; almost predatory, a few types of larvae damage plants. A pair of barbs on its back, when the capture prey can hook around the cave, to prevent being dragged prey outside the cave, it is "camel bug" in the title. A total of three larval instars, soil tunneling to "passive" approach through small insects attack and prey dragged into the cave eating, food residue will be cleared from outside the cave.

虎甲的饲养
A colorful tiger because, pupa peculiar shape and easier feeding, become more popular recently one insect pet. Feeding points are as follows: General digging wild larvae were reared. Use small containers kept separate, moist soil compaction up to 5-10 cm thick around (preferably water once drenched the soil more solid, but the bottom of the container do not water), and finally into larvae, and soon it will dig their own caves . Appear in the mouth of the cave to see the larvae can begin feeding it. Tiger beetle larvae do not disturb the case, put in the hole near the small insects live up to the discretion climbed tiger beetle larvae attack range, tiger beetle larvae to capture prey will eat it quickly pulled into the cave, the residue left after eating will be thrown outside the cave. Predatory larvae, can be fed live insects such as: large ants, crickets young nymph, cabbage butterfly larvae, just bread insect larvae molt. Pupal period of about 14 days. A small tiger predation of adult insects, good flying and run, requires more than open space, relatively trouble feeding arrangement.

Brief introduction
A tiger (tiger beetle) is Coleoptera (Coleoptera) tiger beetles (Cicindelidae) insects collectively, for the medium-sized beetles, generally have bright colors and gorgeous spots. Large head, front-mouth, palate big, so cross. A tiger is a carnivorous insect, daytime activities, often feeding insects on the road, when people close, often flying a short distance ahead, so there is the common name stumbling block, lead the way insects said. Common types are China tiger A multi-level type of tiger. Coleoptera (Coleoptera) tiger beetles (Cicindelidae) beetle, about 2,000 species, because the habits of larvae and adults bulimia, hence the name. Vertical larvae secluded cave, sometimes as deep as 67 centimeters (2 feet). In Xuekou awaiting prey, often including insects and spiders, with a sickle-shaped palate catch live prey. Larval abdomen with a pair of hook fixing hole wall, struggling to avoid being pulled catch outside the cave. Edible prey towed to the hole bottom. Adult slender, about 10 to 20 mm (2/5 to 4/5 inch); foot long, prominent eyes, and thus visual acuity. Many species of blue, green, orange, or scarlet, with iridescent sheen. Multi color change is caused by the release of pigment formation exoskeleton, and is difficult to control the color of the skin characterized by the formation of the exoskeleton. Running and flying fast, it is easy to catch a variety of prey. When caught, a tiger will bite hard palate with a long, very painful. Although over the world, but most species distributed in subtropical or tropical regions, as well as common in sunny road or sand. Tiger A common genus (Cicindela) of most species have scroll-shaped markings Coleoptera. Habitat types are usually in sandy coloration, consistent with the surrounding environment. A tiger is running the fastest creatures on land (calculated according to the proportion of body length), 171 times per second moving body length. If you zoom in to the Tiger A human height equal length, its running speed is the speed of a Formula One car more than twice. When speed run, its compound eye structure due to insufficient processing capacity limits and the brain, causing instant blindness, so the process had to hunt prey often stopped to re-locate their prey, and then continue to kill.
A Tiger by colorful, exotic appearance and easier pupae reared to become more popular recently one pet insects. Feeding points are as follows: General excavation wild larvae were reared. Use small containers kept separate, moist soil compaction of about 5-10 cm thick (preferably water once drenched the soil to make more solid, but not to the bottom of the container water), and finally into larvae, and soon it will own burrowing . Appeared in the cave to see the larvae can begin feeding the mouth. A tiger does not disturb the case of larvae, placed near the entrance to the discretion of living insects crawled tiger beetle larvae attack range, after the tiger beetle larvae to capture its prey would quickly pull into the cave eating, after eating the remaining residue will be thrown outside the cave. Predatory larvae can be fed live insects such as: large ants, crickets young nymph, cabbage butterfly larvae, just bread insect larvae molt. Pupal period of about 14 days. A tiger prey on small and medium sized adult insects, good flying and running, you need to open space ratio, feeding arrangement is relatively cumbersome.
