Abstract: In the Czech Republic, A. nebulosus occurs in coniferous, deciduous as well as in mixed forests, in lowland forests and even on forest-steppe habitats. Larvae occur mainly on Picea sp., Pinus sp. and Abies sp.; adults occur on the same tree species and also on Larix sp., Quercus sp., Salix sp. and Fagus sp. Adults overwinter in the bark of several coniferous trees with thicker bark (mainly Pinus sylvestris L. and Larix decidua Mill.) where they are hidden in cracks. Woodpeckers attack such trees with masses ofA. nebulosus very intensively. In five localities with Malaise traps in the Nízký Jeseník Hills, the flight activity started at the beginning of May and ended in mid-June with the peak at the end of May and beginning of June in 2005. In 2006, the flight activity started later in mid-May and lasted to the beginning of July but was interrupted by cold and rainy weather. At higher altitudes were beetles sampled only in the first half of June in 2006. The size of males and females is very similar. In total, pronotum width of males varied between 0.85 mm and 2.40 mm, and females between 1.00 mm and 2.30 mm. There is no statistically significant difference between them. The equal sex ratio found in our material could confirm the fact that the flight activity of both sexes is the same.
