The Buprestidae is a large family of beetles with some 15,000 species, divided into 450 genera, most of these are tropical but about 120 are resident in Europe. These beetles that are commonly called Jewel Beetles or Metallic Wood-boring Beetles due to their bright colours. They range in size from 1 to 35 mm in length, have large eyes, and short antennae, and the head is sunken into the thorax. The larvae bore into wood, feeding on the inner bark, sapwood, or heartwood, this stage can last several years, especially in larger species or hardwoods. Some species are serious pests of timber, fruit trees, or ornamentals. Adults often feed on foliage, pollen, or nectar, though some species do not feed at all.

Their metallic colouration, of the Buprestidae, results not from pigments but from microscopic structures in the cuticle that reflect and refract light (structural coloration). In some cultures, their iridescent wing cases are used in art, embroidery, and jewelry. The adults are often most active in sunny, warm environments, which enhances their shimmering appearance.
