Northward expansion: four new Odonata species for Latvia

This paper confirms four Odonata species (Lestes barbarus, Sympecma fusca, Crocothemis erythraea, and Sympetrum meridionale) as new for Latvia, three having increased the northern edges of their range due to the warming climate. The records of C. erythraea and S. meridionale are currently the most northerly records ever. While only individual records of L. barbarus, C. erythraea, and S. meridionale were made, S. fusca was found at eleven sites throughout the country.
