Odonata

Atlas of Odonata of Germany – For the first time, we present a complete overview about the distribution of all dragonfly species occurring in Germany. The atlas is based on a data collection compiled during 2007-2012, which was organized by the atlas-working-group of Gesellschaft deutschsprachiger Odonatologen. The database comprises more than 1.16 million point locality data sets delivered by more than 2,900 persons from all 16 federal states. Whereas few data date back as far as the year 1800 most are more recent; most recent data are from 2011, for some species with current drastic distribution changes from 2013. While only 1 % of the records are from the first 150 years, more than 63 % are from later than 1995. Since 1995 data were recorded for 79 of the 81 species occurring in Germany, while Coenagrion hylas and Onychogomphus uncatus were only observed in Germany before 1995 and are now considered as extinct.
The atlas comprises distribution maps for all of the 81 dragonfly species. Each map grid square represents a so called Messtischblatt (MTB) with an area of ca 130 km². For each species the distribution situation is depicted for three time periods: before 1980, 1980-1995, and after 1995. The atlas also includes species monographs where the vertical and horizontal distributions in Germany (according to the database) as well as habitat, life cycle, population trends, and threats are described. Finally, an overview about records of exotic dragonflies recorded in Germany is presented.
Basing on this atlas the Red List of Odonata of Germany is presented not in this article but
in this issue as well as an extensive presentation of fossil odonate records from Germany.

Mit diesem Atlas wird erstmals für Deutschland eine umfassende Verbreitungsübersicht der Libellenfauna dargestellt. Er basiert auf einer Datensammlung, die von einer insgesamt 25 Mitglieder umfassenden Arbeitsgruppe der Gesellschaft deutschsprachiger Odonatologen (GdO) zwischen 2007 und 2012 koordiniert wurde. Dabei wurden insgesamt mehr als 1,16 Millionen Datensätze von mehr als 2.900 Personen aus allen 16 Bundesländern in einer zentralen Datenbank zusammengetragen. Die Daten stammen aus dem Zeitraum 1800 bis 2011, für einzelne Arten mit einer starken aktuellen Verbreitungsdynamik auch bis 2013. Während auf die ersten 150 Jahren dieses Zeitraumes nur etwas mehr als 1 % der Datensätze entfallen, wurden mehr als 63 % nach 1995 erhoben. Für 79 der 81 bislang in Deutschland im Freiland nachgewiesenen Arten liegen aus dem Zeitraum nach 1995 Daten vor, lediglich Coenagrion hylas und Onychogomphus uncatus wurden seitdem nicht in Deutschland beobachtet. Die Darstellung der Verbreitung erfolgt auf der Basis von Rasterkarten. Die Rasterfelder repräsentieren dabei jeweils ein Messtischblatt (MTB) mit einer Fläche von etwa 130 km². Die Verbreitung der Arten wird differenziert für die drei Zeitabschnitte „vor 1980“, „1980-1995“ und „ab 1995“. Insgesamt liegen für mehr als 98 % der knapp 3.000 Rasterfelder Libellendaten vor. Für jede der 81 Arten werden Artmonographien vorgelegt. Dabei werden auf der Grundlage der vorliegenden Daten, der Verbreitungskarten sowie von Literaturangaben für Deutschland die horizontale und vertikale Verbreitung, Habitatansprüche sowie Lebenszyklus beschrieben und Angaben zur Bestandsentwicklung und Gefährdung gemacht. Abschließend wird ein Überblick gegeben über die exotischen Libellenarten, die bislang in Deutschland nachgewiesen wurden.
Der Atlas ist Grundlage für die im gleichen Supplementband erscheinende Rote Liste und wird ergänzt durch eine umfassende Darstellung der bislang in Deutschland erbrachten fossilen Libellennachweise.

The objective of the present study is to explore the diversity of dragonflies and damselflies (Odonata) in Athagarh Forest Division, Odisha. Odonates were studied from January 2015 to March 2015. In this survey a total of 56 species of odonates were recorded, including 31 species of dragonflies (Sub order: Anisoptera) belonging to 3 families and 25 species of  Damselflies (Sub order: Zygoptera) belonging to 5 families. Among these species, Libelluidae and Coenagrionidae
were the dominant families with maximum number of species being 26 and 17 respectively.

Odonata are freshwater insects spread world-wide. Tropical areas are high Odonata diversity areas. However, there has not been accumulation of extensive baseline data on spatial distribution of these insects from such places. Maharashtra, the third largest state of India, harbors a variety of land-use and occupies six biogeographic provinces. We carried out Odonata surveys in Maharashtra during 2006–2014. Compilation of all these studies along with other authenticated records resulted in a checklist of 134 species of Odonata belonging to 70 genera representing 11 families. The highest numbers of species were recorded from the Libellulidae (48 species) and Gomphidae (22 species) families. A previous study had reported 99 species of Odonata from the Maharashtra state considering records from early 1900’s to 2012. Our observations across the state add 33 species to this list. Maharashtra forms a unique source of Odonata diversity and our observations support the importance of this region in providing valuable habitats for Odonata. Here, we discuss several of the new records, how global surveys might help fill the local gap in species distributions, how secondary data deposited through crowd-sourcing can help and what it offers to conservation.

Larvae of almost all of the 5,680 species of the insect order Odonata (dragonflies and damselflies) are dependent on freshwater habitats. Both larvae and adults are predators. The order is relatively well studied, and the actual number of species may be close to 7,000. Many species have small distributional ranges, and are habitat specialists, including inhabitants of alpine mountain bogs, seepage areas in tropical rain forests, and waterfalls. They are often successfully used as indicators for environmental health and conservation management. The highest diversity is found in flowing waters in rain forests of the tropics, the Oriental and Neotropical regions being the most speciose. This paper discusses diversity, summarises the biogeography of dragonflies in the different biogeographical regions and gives the total number of species and genera per family per biogeographical region. Examples are given of areas of particular diversity, in terms of areas of endemism, presence of ancient lineages or remarkable recent radiations but no well-based review of areas with high endemism of dragonflies is available so far. The conservation status of dragonflies is briefly discussed. Species confined to small remnants of forest in the tropics are most under threat of extinction by human activities.

t 'Kleine Loopveld (KLV) is een stadspark, gelegen aan de rand van de wijk Buitenveldert in Amsterdam . KLV maakt deel uit van een ecologische verbindingszone genaamd ecolint, gelegen op de grens van de stad Amsterdam. In de 2013 is het landschapsontwerp van het KLV veranderd: de oevers van een aantal bestaande poelen zijn aangepast en er zijn een aantal nieuwe poelen aangelegd. Om de gevolgen van deze veranderingen op de Odonata fauna te evalueren, hebben we een onderzoeksprogramma ontworpen waarin het voorkomen van adulten (imago,s) vergeleken wordt met het succesvol “uitsluipen” van libellenlarven, met behulp van larvenhuidjes (exuviae). Imago's en  exuviae worden beide bemonsterd, gedetermineerd tot op soort, geteld en in lijsten met elkaar vergeleken. Het idee hierachter is dat het voorkomen van imago's een mogelijkheid tot kolonisatie is, en het uitsluipen van libellenlarven een succesvolle vestiging van een soort in het gebied betekend. We hebben 12 soorten Waterjuffers (Zygoptera) n=4 en Libellen (Anisoptera) n=8 gevonden in de onderzoeksperiode van mei tot augustus 2014, verdeeld over vier verschillende poelen in KLV. Bij vergelijking tussen volwassenen en  larvenhuidjes zijn een verschillend aantal soorten gevonden. De samenstelling van de gemeenschappen in de 4 poelen verschilde ook. Ook zien we verschil in gebruik van nieuwe oevers met reeds bestaande oevers van de aangetroffen soorten.

Odonate diversity was investigated at Pariej wetland of Gujarat during 2014 to 2015. Total 29 species belonging to two suborders, five families and 22 genera were recorded. Total 9 species of Zygoptera (damselflies) and 19 species of Anisoptera (dragonflies) were recorded. Twelve species were common, 13 were uncommon and 4 were rare.

The Final Species Reports were prepared under the IPA Project ’Establishment of NATURA 2000 network in Monte-negro’ which provided technical assistance to the Ministry of Sustainable Development and Tourism (MoSDT) and the Nature and Environmental Protection Agency (NEPA). A team of 19 species experts collected field data on Annex II species of the Habitats Directive during the field seasons 2017 and 2018. The research was focused on nine the so-called ‘Key Biodiversity Areas (KBAs).

The purpose of the Final Species Reports was to evaluate the distribution and current state of populations of species surveyed under the project based on findings during two vegetation seasons. The documents represent a summary of the expert´s own work or work of group of experts, including best expert’s opinion, and are a part of the final report of the project.

Stunden von über 400 Melderinnen und Meldern des AK Libellen NRW erarbeitet. Die Libellen wurden erfasst und die Beobachtungsdaten ausgewertet. Tausende Fundpunkte informieren über die Verbreitung der in Nordrhein-Westfalen heimischen Libellenarten. Das Buch ist damit die Grundlage für weitere Fragen der naturkundlichen Landesforschung und wird in Zukunft ein wichtiges Standardwerk darstellen, um die Entwicklung der heimischen Libellenbestände zu überwachen. Für Ökologen, Biologen, Studierende und interessierte Laien wird dieser Atlas für lange Zeit ein wichtiges Nachschlagewerk zur Libellenfauna Nordrhein-Westfalens sein. Das Buch ist allgemeinverständlich geschrieben und sehr ansprechend gestaltet. Es enthält viele wertvolle Informationen zur Biologie dieser schönen Insektenarten und ist somit bestens geeignet, alle Menschen für die heimischen Libellen zu begeistern.

Most of the limnological studies in India have focussed on a few taxa of large, permanent water bodies, and pond ecosystems, and related temporary water bodies are neglected. We present here a faunal inventory, with representative photographs, for a single, small temporary pond, reporting over 125 species of strictly aquatic fauna and 25 species of associated fauna, even though we did not identify some groups such as Protozoa, Diptera and nymphs of Odonata, etc. The identified species belong to seven taxa of vertebrates and invertebrates together. Arthropoda and Rotifera were the most species rich groups, observed with 83 and 45 representatives, respectively. Coleoptera were the most numerous in terms of species number. Such a small water body holds some endemics as well as otherwise very rare animals and so deserves better attention. We also highlight the potential and importance of such habitats for research and conservation.

Records of 57 odonate species group taxa obtained at 76 sampling sites during several field surveys between 2012 and 2016 are presented, corresponding to more than three quarters of the Georgian odonate fauna. Ischnura fountaineae is a new addition to the coun try's list. Sympetrum arenicolor was recorded for the second time and Aeshna serrata was found at two further lakes on the Javakheti volcanic plateau. For other species, such as Cordulia aenea and Leucorrhinia pectoralis only very limited and mainly old data was available. In addition, new records for Coenagrion ponticum, an endemic of the Caucasus region, as well as for Coenagrion pulchellum and C. scitulum, both rare in the Caucasus region, are given. Further information on the globally threatened gomphids Onychogomphus assimilis and O. flexuosus are presented, including the first exuviae records of the latter in Georgia. New findings of the nominate taxon of Sympetrum vulgatum provided indications on regional distribution pattern and spatial delimitation from ssp. decoloratum. Further records of Pantala flavescens suggested rather regular occurrence in Georgia, being an integral part of the Georgian dragonfly fauna. The existence of small isolated pockets of Calopteryx splendens ssp. tschaldirica inside the core area of ssp. intermedia in Georgia was confirmed as well as several individuals of ssp. tschaldirica from the Georgian stronghold of the taxon in the Javakheti volcanic plateau showing entirely hyaline wings, phenotypically resembling ssp. waterstoni. Against the background of general taxonomic difficulties with the Calopteryx splendens taxa complex, both phenomena are discussed.

Das Verbreitungsgebiet reicht von Portugal im Westen bis zum Ural sowie dem Schwarzen und Kaspischen Meer im Osten. Im Norden erreicht die Art Südschwe den und Südfinnland. In Südeuropa liegen die bekannten Vorkommen meist weit verstreut. Die südlichsten Nachweise gelangen auf der PeloponnesHalbinsel.

Data related to the 41 species of the dragonfly fauna of central and southwestern
Republic of North Macedonia and nearby Albania, gathered during the
post European Congress on Odonatology 2012 fieldtrip on July 6-13th, 2012 are
presented. The Ohrid – Prespa region was particularly investigated. The majority
of previous data available for this area is old and outdated. Additionally, recent degradation of habitats, combined with sporadic records of some patrimonial
species made new surveys necessary. The presence of Gomphus schneiderii Selys,
1850 and S. flavomaculata in the region was confirmed whereas L. pectoralis was
not found again. Conversely, Coenagrion scitulum (Rambur, 1842) was observed
in Albania for the first time. The national Odonata checklists contain now 63
species in Republic of North Macedonia and 59 in Albania.
