Please answer the following question: Information:  - Cicindela trifasciata sigmoidea , commonly called the mudflat tiger beetle , is a species of tiger beetle . The specimen shown in the picture was raised in captivity in Pasadena , California , an inland city . Its parents were captured at the Mugu Naval Base marsh in Ventura , California in 2003 ( for a UCLA Masters thesis ) . This species of tiger beetle was found to be rare in 1982 by a study conducted by the Los Angeles County Natural History Museum . The leading entomologists for the 1982 study were Christopher Nagano and James Hogue . This tiger beetle , the second smallest of the six Cicindela in the Naval Base , is now extremely rare .  - Cicindela, commonly known as common tiger beetles are generally brightly colored and metallic beetles, often with some sort of patterning of ivory or cream-colored markings. They are most abundant and diverse in habitats with sandy soil (though some prefer clay), and very often near bodies of water, even if seasonally transient; along river, sea and lake shores, on sand dunes, around playa lakebeds and on clay banks or woodland paths.  - Beetles are a group of insects that form the order Coleoptera. The word "coleoptera" is from the Greek , "koleós", meaning "sheath"; and , "pterón", meaning "wing", thus "sheathed wing", because most beetles have two pairs of wings, the front pair, the "elytra", being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen. The order contains more species than any other order, constituting almost 25% of all known animal life-forms. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. The largest taxonomic family, the Curculionidae (the weevils or snout beetles), also belongs to this order.  - Tiger beetles are a large group of beetles known for their aggressive predatory habits and running speed. The fastest species of tiger beetle, "Cicindela hudsoni", can run at a speed of 9 km/h (5.6 mph), 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.
