Abstract
The aim of this study was to determine the species composition of dragonflies (Odonata) of 8 motorway retention ponds situated in the Mińsk Mazowiecki district (Province of Mazovia). A total of 36 species were found (48.6% of the Polish odonate fauna), 24 of which were classified as autochthonous or probably autochthonous. The most abundant species in the ponds were Coenagrion puella, Erythromma viridulum and Ischnura elegans. Two species protected in Poland were recorded – Leucorrhinia albifrons and Sympecma paedisca. The records of Sympetrum depressiusculum, S. meridionale and Crocothemis erythraea were the first from the Mińsk Mazowiecki district. The ponds exhibited a considerable qualitative faunistic similarity. As the odonate fauna of the individual ponds was qualitatively poor, these offered suitable habitats for only a small number of dragonfly species. This was due, among other things, to the small surface areas of the ponds and the inappropriate management of the plant succession in them. As the species found were mostly eurytopes and common ones, the ponds are unlikely to enhance the regional dragonfly diversity. To date, there have been no published records of the odonate fauna of motorway retention ponds in Poland, so the present paper provides a comparative background for further research in this field. In addition, these results add to our knowledge of the dragonfly fauna of both the Mińsk Mazowiecki district and two hitherto poorly studied UTM squares (EC38, EC48), within which many species were found for the first time.
