Tiger beetles or the Cicindelidae are a family of beetles 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 Oriental (Indo-Malayan) region, followed by the Neotropics. While historically treated as a subfamily of ground beetles (Carabidae) under the name Cicindelinae, several studies since 2020 indicated that they should be treated as a family, the Cicindelidae, a sister group to Carabidae, within the Adephaga.
In the mid 19th century, Carolus Linnaeus, a Swedish biologist and physician known as the father of modern taxonomy, formally named the first tiger beetle species. Later, field naturalist Thomas Say became the first American to analyze tiger beetles in the field during a period when it was dangerous to conduct field work in America. After decent amounts of data collection, beetle specialists then began to publish articles about tiger beetle taxonomy that was disseminated for other researchers specializing in the research area.
Description
Well-known genera include Cicindela, Tetracha, Omus, Amblycheila and Manticora. Cicindela has a cosmopolitan distribution.
Many tiger beetles have large bulging eyes, long slender legs and large curved mandibles. 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, which live primarily in the dry regions of southern Africa, are the largest in size.
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. All tiger beetles are predatory, both as adults and as larvae. They prey on nearly anything they can catch, including other beetles, hoppers, ants and...
