About Brachyta interrogationis (Linnaeus, 1758)
Brachyta interrogationis can reach a body length of approximately 9–19 millimetres (0.35–0.75 in). These beetles have a completely black body, including the head, thorax, and legs. Their pronotum is convex and marked with dense punctuation. The legs are relatively long and slender. The elytra of this species show very high variability, and over 150 varieties have been described. While elytra may be fully black or fully yellow in some individuals, they are usually brownish-yellow, with black spots on the scutellum, two longitudinal arcuate black bands, and additional black spots on the sides and apex. Antennae of this species are made up of 5 to 11 segments. This species mainly occurs in Central Europe (including Austria, Northern Czech Republic, Finland, France, Eastern Germany, Northern Italy, Norway, Southern Poland, Eastern Slovakia, Sweden and Switzerland), the Caucasus, and extends east through Western Russia, Kazakhstan, Siberia, Mongolia, Manchuria, Korea and Japan. In Europe, Brachyta interrogationis is a boreal-mountainous species, ranging south to the Italian and French Alps, and north to the Arctic Circle. In the Alps, these beetles can be found at elevations up to 2700 meters above sea level.
