Coenagrion armatum (CHARPENTIER, 1840) belongs to the critically endangered species in Poland. The main reasons for its regress are: drying out the habitats due to the climate and anthropopression as well as eutrophisation and the changes of space structure and species composition of veg- etation associated with this (BERNARD et al. 2009). The number of sites of this species in Poland is underestimated...
Coenagrion ornatum is a critically en- dangered species in Poland.

The authors discuss three localities of Orthetrum brunneum in northern Poland (54°29'—54°48’ N, 18°15'—18°33' E). This is the first data from Poland from the area above 54° N, situated over 1.5 degree of latitude towards the north than the sites known so far. The distribution of the species in northern part of Central Europe is also analyzed.
