Ecology and presence in Slovenia
The species occurs in the mountain ranges of central and southern Europe (Pyrenees, Alps), the Carpathians, the Balkans, Siberia, Manchuria and Japan. In Slovenia, the species has been found in the Julian Alps at 1700 m a.s.l. on Pinus mugo, and several times in traps at Brdo pri Kranju (Figure 139). Hosts: Pinus mugo, P. cembra, P. heldreichii, P. sibirica, P. pumila and P. peuce. The species develops one generation per year. It bores star-shaped tunnel systems with 3-5 maternal galleries. Adult length is 2.2-2.8 mm. Morphologically, the species is similar to P. bistridentatus, but for reliable determination it is often necessary to measure the length and width of the elytra. The species is rare and of no economic importance in Slovene territory.
