Southern hawker is one of the most eurytopic dragonfly specieACAs using all types of waters for its development. The observations of this species inhabiting pools made during the mud bath of boars (Sus scrofa) are given. This phenomenon was observed in 2006 in Masovia and the east Sudety Mts.
Report on nature impressions from the expedition to the northern Masovia in the frames of „Atlas of the distribution of the dragonflies (Odonata) of Poland" project. The studies covered 124 study sites and resulted in recording 55 dragonfly species. However, the studied area was strongly transformed - especially this referred to small water courses. Melioration and pollution were probably the main reasons why Calopteryx virgo was found as a very rare species. Erythromma viridulum, Lestes barbarus, Aeshna juncea, A. subarctica elisabetluie, A. viridis, Orthetrum albistylum and O. brunnewn were the most interesting species recorded during studies.
Short note on horizontal and vertical parameters of the position of Ophiogomphus cecilia exuviae in the bank zone of small lowland river. The measurements of 111 exuviae positions were made. The average height on whitch exuviae were found was 77 cm (min. 11 cm, max. 172 cm, most often from 60 to 120 cm), the average distance from the bank line was 43 cm (min. 0 cm, max.210 cm, most often from 0 to 50 cm )
4th All-Polish Odonatological Symposium took place in Brda by the River Brda in Tucholskie Forests. There were 18 participants involved. During three days of the conference the problems connected with standardisation of the methods used in odo­natological studies as well as larval and exu- vial identification were discussed. The main task of the meeting was the practical introduction to the analysis of dragonfly faunistic composition of some study sites which were visited during a daylong field excursion.
In the year 1825 and 1840 Toussaint de CHARPENTIER published two very important for European odonatology works describing new species of dragon+ies. For 10 of them Śląsk (Silesia) was established as locus ty- picus, thus typical materials being the basis of species description came from the areas of Poland. CHARPENTIER lived and worked in Brzeg, in the vicinities of Opole.
