New faunistic data on the distribution of 21 bug species from the Coreoidea superfamily are presented. Stictopleurus crassicornis has been reported for the first time from the Bieszczady Mts.
Analysis of 531 nest cards (Polish Nest Record Scheme) of the Great Spotted Woodpecker, obtained in the years 1970–2003 is presented here. The data is derived from almost the whole of Poland, except for the Białowieża National Park. From the material processed for the purpose of this study, the Great Spotted Woodpeckers appear to nest in various types of wooded habitats, especially in forests and they are very flexible in their choice of nesting sites, both in terms of age of tree stands and intensity of human penetration. As a rule, woodpeckers breed mostly in holes made in deciduous trees (oak, birch, and alder). More than 95% of nests were excavated in tree trunks, primarily in dead or weakened trees. Woodpeckers excavated their nest in the range of 0.5–19 m above the ground, with more than 75% of them found in the narrower range from 1–7 m. The height of cavity above the ground did not depend on tree species or vegetation type and was also weakly correlated with the height of tree stands. The openings of cavities showed no statistically significant differences in their geographical orientation. Although the information about woodpecker nests, gathered in the Nest Record Scheme does contain certain errors (such as “habitat preferences” of observers), the obtained results provided a better insight into the nesting ecology of this species in Poland.
The localités of 15 species new for the fauna of "Góra Św. Anny" Landscape Park in the Opole voivodeship are presented. The surveys were conducted mostly in the kserothermic grassland, in the season 1998-2000. Some of the mentioned species are very rare in Upper Silesia.
New data on the occurrence of 14 Heteroptera species are presented. One species is recorded for the first time in Lower Silesia and Upper Silesia, 3 species are reported for the first time from Eastern Sudetes.
