CALOMERA DECEMGUTTATA TIGER BEETLE As tiger beetles are often colorful and diurnal, they have attracted the attention of academics, citizen scientists, and nature-lovers. For example, there is an entire journal ''Cicindela'' devoted exclusively to this group, and highlights the public interest in these animals which belong to the best known insects . As several tiger beetles are known to be in strong decline, they became one of the most suitable insect groups for conservation biology including action plans for . Numerous species are listed in European Red Lists or in the U.S. Endangered Species Act.
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, Cicindela 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 Oriental (Indo-Malayan) region, followed by the Neotropics.
Tiger beetles often have large bulging eyes, long, slender legs and large curved mandibles. All are predatory, both as adults and as larvae. The genus Cicindela has a cosmopolitan distribution. Other well-known genera include Tetracha, Omus, Amblycheila and Manticora. 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 colored, while the other genera mentioned are usually uniform black in color. Tiger beetles in the genus Manticora are the largest in size of the subfamily. These live primarily in the dry regions of southern Africa.
The larvae of tiger beetles live in cylindrical burrows as much as a meter deep. They are large-headed, hump-backed grubs and use their humpbacks to flip backwards, for the purpose of capturing prey insects that wander over the ground. The fast-moving adults run down their prey and are extremely fast on the wing, their reaction times being of the same order as that of common houseflies. Some tiger beetles in the tropics are arboreal, but most run on the surface of the ground. They live along sea and lake shores, on sand dunes, around playa lakebeds and on clay banks or woodland paths, being particularly fond of sandy surfaces.
