Abstract
The Masurian Lakeland is well known for its tourist values, with plenty of lakes, forests, and historic sites offering a wide variety of activities. It is also an area with outstanding nature linked to its early postglacial geomorphology – most notably lakes, a dense net of streams and rivers, peatbogs, and therefore a great diversity of hydrogenic plant associations. Being located in the north-east of Poland it is characterized by its climate, thanks to which many relict boreal species of plants and animals have their refugia or limits of compact range in the region. Despite its high natural value, Heteroptera remained poorly studied for many years with only 6 species being reported from the area by the end of World War II. This situation has improved in the last 70 years, but the number of species known from the Masurian Lakeland is still very low when compared to other zoogeographical regions of Poland. With that in mind, we decided to carry out new research on true bugs in this area. The material for the study was collected from 35 sites and represents 129 species of Heteroptera with 15 species being recorded for the first time in this region.
