DISCUSSION

Representatives of genus Osmoderma, as well as other species that depend on rare and endangered microhabitats, such as old, hollow trees, have a high conservation value (Audisio et al. 2007; Nieto & Alexander 2010; Maurizi et al. 2017). Five species were distinguished in Osmoderma eremita s.l. complex in Europe and O.barnabita is one of the species which forms this complex (Ranius et al. 2005; Audisio et al. 2007, 2008; Svensson et al. 2009; Carpaneto et al. 2015; Zauli et al. 2016; Landvik et al. 2017; Maurizi et al. 2017).

Since 1992 O.eremita was listed as priority species in Annexes II and IV of the EU’s Habitat Directive (Luce 1996, Ranius et al., 2005); at the same time, O.barnabita, as part of the O.eremita complex, is subject to all the environmental requirements of the Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora (Audisio et al. 2008, 2009, 2014; Carpaneto et al. 2015; Maurizi et al. 2017) and the Bern Convention (Annex II). This species also is included in the category „Near Threatened” in the IUCN European Red List of Saproxylic Beetles (Alexander et al. 2010). At the local level, the hermit beetle is listed in the Red Data Book of Lithuania (Rašomavičius, 2007, 2021; Ivinskis, 2006, 2015), and is also an indicator species of key forest habitats (Ivinskis et al. 2018).

Despite the various measures to protect the species, the current population trend of this species in Europe is decreasing (Audisio et al. 2007, Alexander et al. 2010).

The territory of Lithuania plays an important role in the occurrence of O.barnabita in the Boreal region. According to Species assessments at EU biogeographical level, the estimated size of O.eremita complex inhabited area in Lithuania is 285 km 2, which is 24.74 % of the total population in the Boreal region.

This article compiles all the historical information, including mentions of the occurrence of O.barnabita in Lithuania, and presents the most recent data on the occurrence of O.barnabita, based on field studies of habitats suitable for this species. Despite the significant nature conservation value of the territory of Lithuania, there is much less data on protected species, including the occurrence of O.barnabita, then in Latvia, and the investigation of hermit beetle in Lithuania was insufficient for a long time (Davenis et al. 2018; Valainis et al. 2021). Purposeful study of the beetle fauna, as well as actual information about hermit beetles, appears in the scientific literature only in the middle of the twentieth century. Further research was limited to the indication of new localities, and data on the occurrence, biology and ecology of this species in Lithuania were not summarized up to the early 21st century when Ehnström (2003) and Tamutis (2005) were published reviews on rare and protected beetles in Lithuania. In total, only one study of hermit beetles has been conducted in Lithuania, and extensive data have been published as a result (Davenis et al. 2018). In recent years, scientific interest in the occurrence of hermit beetle and problems of species conservation has increased and many new localities were discovered. The ecological network for species dependent on ancient broadleaf trees using O.barnabita as a model species was published recently (Valainis et al. 2021). In this article, the area suitable for the occurrence of hermit beetles were identified not only in Lithuania but also in Latvia. In our publication, we provide new data on the prevalence of O.barnabita, as well as provide the most recent and complete map of the occurrence of this species in Lithuania, based on all the information available to date (Figure 1). These data will significantly complement the knowledge about the population of O.barnabita in Lithuania and will facilitate further research in the country.
