Ecology and presence in Slovenia
The species is found in southern and central Europe, the Crimea, the Caucasus, Asia and the Afrotropical region. Siegel (1866) states that the species was “rare in Carniola, mostly under pine and spruce bark”. More recent records are found mainly in Gorenjska and the Slovene part of Istria, specimens were caught in traps (Figure 5). Hosts include Pinus sylvestris, P. pinaster, P. nigra, P. pinea, less frequently Picea abies, P. orientalis, occasionally also Larix decidua. In Slovenia, the species has been found on P. nigra, P. sylvestris and P. abies. A phloemophagous species, it develops 1 to 3 generations per year. Length (adultus) is 2.5-3.0 mm. The elytra descend to the posterior sternite in an arc at the apex (Figure 4).
