The adults grow up to 8–23 millimetres (0.31–0.91in) and can be encountered from May through August, completing their life cycle in two to three years. Head and pronotum are usually black, while elytrae are black or brownish, with various longitudinal ridges (hence the specific name).
They are polyphagous in coniferous trees (mainly feeding on Pinus sylvestris, Pinus mugo and Pinus nigra, but also on Picea abies and Abies or Larix species). Larvae develop under bark of host plants, later in dead branches and stumps of trees.
Pinus albicaulis, known by the common names whitebark pine, white bark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, and Rocky Mountains. It shares the common name "creeping pine" with several other plants.
Pinus nigra, the Austrian pine or black pine, is a moderately variable species of pine, occurring across Southern Europe from the Iberian Peninsula to the eastern Mediterranean, on the Anatolian peninsula of Turkey, Corsica and Cyprus, as well as Crimea and in the high mountains of Northwest Africa.
Picea abies, the Norway spruce or European spruce, is a species of spruce native to Northern, Central and Eastern Europe.
The Northern Anatolian conifer and deciduous forests is a temperate coniferous forests ecoregion located in northern Anatolia, Turkey.
Spruce-pine-fir (SPF) is a classification of lumber that can be traded on commodities exchanges.
Lophodermium is a genus of fungi within the family Rhytismataceae. The genus contains 145 species and has a global distribution. Species of this genus are usually observed producing zone lines, conidiomata and ascomata on dead fallen leaves, but at least some are known to colonize living leaves. In many cases they then live inside the colonized leaf as a symptomless endobiont, where they are regarded as detritivores utilising dead plant matter. In a few cases they may kill all or part of the leaf prematurely, and there is a substantial literature dealing with those species as plant pathogens. The genus infects many different plant families but with a notable concentration in the family Pinaceae; many Lophodermium species are restricted to a single host genus, but some, particularly those infecting grasses, may infect several genera. Some are economically important plant pathogens, such as those that cause needlecast disease in European Black Pine, Scots Pine and Red Pine in forestry and christmas tree plantations. In these species, notably L. pinastri and L. seditiosum, the fungal spores disperse and infect the pine needles in late summer, which turn brown by the following spring and then fall off.
The South Apennine mixed montane forests is an ecoregion in the southern Apennine Mountains of southern Italy and Sicily. It has a Mediterranean climate, and is in the Mediterranean forests, woodlands, and scrub biome.
The Western Himalayan subalpine conifer forests is a temperate coniferous forests ecoregion of the middle and upper elevations of the western Middle Himalayas of Nepal, India, and Pakistan.
Stictoleptura rubra, the Red-brown Longhorn Beetle, is a species of beetles belonging to the family Cerambycidae.
Gaurotes virginea is a species of the Lepturinae subfamily in the long-horned beetle family.
Rutpela maculata, the spotted longhorn, is a beetle species of flower longhorns of the family Cerambycidae, subfamily Lepturinae.
Anthaxia quadripunctata, the Metallic wood-boring beetle, is a species of jewel beetles belonging to the family Buprestidae, subfamily Buprestinae.
Hylastes ater is a species of beetle in the family Curculionidae, the true weevils. It is a bark beetle, a member of the subfamily Scolytinae. Its common name is the black pine bark beetle. It is native to Europe and parts of Asia, including China and Korea. It is known as an introduced species in many other regions, including Australia, New Zealand, the Americas, and South Africa. It is a pest of pines and other trees, and it is widespread in areas where pine trees are cultivated. The species "is an important threat to the biosecurity of all forested countries."
The Anatolian conifer and deciduous mixed forests is an ecoregion located in southwestern Anatolia, Turkey. It has a Mediterranean climate, and is part of the Mediterranean forests, woodlands, and scrub biome.
Dendroctonus valens, the red turpentine beetle, is a species of bark beetle native to the forests of North America, Mexico, Guatemala and Honduras. It has been introduced to China where it has become invasive. In its native range it causes little damage, but in China it is a destructive pest and has killed more than six million pine trees.
The Alps conifer and mixed forests is a temperate broadleaf and mixed forests ecoregion in central Europe. It extends along the Alps mountains through portions of France, Italy, Switzerland, Germany, Liechtenstein, Austria, and Slovenia. The ecoregion extends from the lower slopes of the Alps to its peaks, which include Mont Blanc, at 4,809 m (15,778 ft) the highest peak in the Alps.
