Stromatium auratum, a widely distributed xerophilic Palaearctic Cerambycid (known from whole Mediterranena region, Caucasus/Transcaucasia, Central Asia, Near East and Iran), has been first described from France as Cerambyx Fulvus by Charles Joseph Villers in 1789 [✧]. Lately was this taxon included in the genus Stromatium and under the name Stromatium fulvum was known for more than 150 years. But due to preoccupation of the name fulvum is its valid species name auratum, used fist by Johann Jakob Ritter von Böber in his description from 1793 (as Saperda aurata) [❖]. The restitution of the taxon S. auratum (Böber, 1793) was published by Maxim Lazarev in 2014 [▽].

Larvae of S. auratum develop in dead wood of many tree species, even when dry, for prolonged time, and their life cycle can take several years. These characteristics facilitate survival even during long overseas travels. The beetles are therefore often carried over long distances in wooden furniture, wood packaging and other wooden material. It is probably reason of the introduction of S. auratum to Subsaharan Africa, North, Central and South America [✮]. The species is considered an important technical pest of processed wood.

Body length:12 - 32 mm
Life cycle:2 and more years
Adults in:May - August
Host plant:polyphagous in dead dry wood of various trees, prefers deciduous trees
Distribution:whole Mediterranean region, Hungary, Romania, Iran, Near East, Caucasus, Transcaucasia

The depicted beetles were reared from a larvae found in a dead branch of Acer sempervirens in Imbros (Ιμβρος) village environs (N35°14′35″ E24°09′48″; 770 m a.s.l., Chania regional unit, Crete, Greece) on June 26, 2018.
