There are 7 species of Lestidae family recorded in the area of Silesian Province. Among them 3 are thought to be rare: Sympecma paedisca, Lestes dryas and testes barbarus. S. paedisca is additionally protected by law in Poland. In the area of Silesian Province it was recorded for the first time in 1959 by Sawkiewicz and Żak in Maciejkowice locality, nowadays it is protected in form of small reserve called „Żabie Doły". The presence of this species in this locality was confirmed by the author of the following paper, who observed a female of S. paedisca in a bizzare tandem with a male of S. fusca. Besides that it was recorded in several new localities, on the contrary to other two species of Lestes genus. Generally they were recorded in smaller number and in less localities than it was in the past. There are many habitats in Silesian Province of types that are preferred by these species, yet a significant decline in their occurrence was observed. The reason for this situation remains unknown and needs to be studied during further research.
