About Grammoptera ruficornis (Fabricius, 1781)
Grammoptera ruficornis reaches an adult body length of approximately 3–7 mm (0.12–0.28 in). Females are both longer and wider than males of the species. As small longhorn beetles, they have elongated, densely punctate bodies including the pronotum and elytra, and their bodies are not significantly narrowed toward the rear. Fine silky hairs cover their elytra, and their eyes lie fairly close to the base of the mandibles. Their basic body color is dark brown or black. They have long yellow-red antennae that are nearly as long as their bodies, with an elongated second segment. Their legs are partially yellow-red, with bulbous two-colored femora; the hind femora may sometimes be entirely black. This species occurs across the Palearctic realm. It is found across most of Europe including Albania, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Moldova, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Ukraine, and the United Kingdom, as well as in the Caucasus, Transcaucasia, Turkey, Azerbaijan, and Iran. These longhorn beetles are associated with deciduous woodland. They can be found in forests, forest glades, pastures, and on old deciduous trees. In the Alps, they rarely grow found above 1,000 metres (3,300 ft) above sea level.
