Wetland ecosystems, including the associated waterbodies, come in all shapes and sizes and all have a role to play. The larger ones, perhaps inevitably, have enjoyed the most attention – it is easy to overlook the many small waterbodies scattered across the landscape. Fortunately, over the last decade, our knowledge and attitude towards small wetlands like ponds has begun to change. We know now that they are crucial for biodiversity This and can also provide a whole range of ecosystem services. -

Zygoptera: Coenagrionidae)
Odonalologica 12(4): 375-379 December I, 1983 Matingisolation in two species of Nehalennia (Zygoptera: Coenagrionidae) D.F.J. Hilton Department of Biological Sciences, Bishop’s University, Lennoxville, Quebec, JIM 1Z7, Canada Received June 24, 1983 / Accepted August 5, 1983 Two black sympatric species of Nehalennia breeding in a spruce-sphagnum bog isolated were effectively from incorrect pairings even though attempts at intermale and interspecific associations were sometimes made. This isolation was probably due to a morphological requirement for the male’s anal appendages to mesh with the female’s mesostigmal laminae. INTRODUCTION Among adult Odonata, vision is considered to be the most highly developed sense and plays an important role in feeding and reproductive behaviors such as and of mating oviposition (CORBET, 1963). Males many species are known to rely upon vision for mate discrimination. For instance, Leucorrhinia dubia (Vander L.) (Libellulidae) males were able to distinguish conspecific females from those of L. rubicunda (L.), apparently solely on the basis of differences in abdominal size, since the body color patterns of both sexes are very similar. In addition, males could distinguish males from females of either species Sometimes visual discrimination (PAJUNEN, 1964). does not prevent occasional instances of interspecies or intermaletandemlinkages. B1CK & BICK (1981) record all published references to heterospecific pairing and show that greater morphological similarity between individuals results in higher incidences of such pairings. Thus, ofthe 93 pairs listed, 11(11.9%) were between membersof different families, 21 between different (22.5%) genera and 61 (65.6%) between different species. Similarly, MOORE (1964) determined that interspecific interactions were greatest between species that looked most similarto the human eye. -

Aeshna Viridis Is an Early Bird – Matutinal Matings in a Crepuscular Species (Odonata: Aeshnidae)*
Matutinal matings in Aeshna viridis 1st June 201637 Aeshna viridis is an early bird – matutinal matings in a crepuscular species (Odonata: Aeshnidae)* Angelika Borkenstein1, Asmus Schröter2 & Reinhard Jödicke3 1 Lebensborner Weg 5, 26419 Schortens, Germany; <[email protected]> 2 Rasenweg 10, 37130 Gleichen, Germany; <[email protected]> 3 Am Liebfrauenbusch 3, 26655 Westerstede, Germany; <[email protected]> Received 26th November 2015; revised and accepted 7th February 2016 Abstract. The hitherto unknown mating activities of Aeshna viridis at dawn are described and photographically documented. At first morning light both sexes arrived at the breed- ing pond flying over dense stands ofStratiotes aloides. Their flight style was of two types: the well-known feeding flight and a slow, low, linear and non-aggressive cruising flight. Cruising individuals sometimes formed mating wheels and the couples left the pond. Shortly before sunrise numerous males started to search for receptive females in the tall herbaceous vegeta- tion near the pond. This non-aggressive flight mode was slow and at knee-height, character- ised by intrusion into dense thickets; we term it searching flight. It ceased within a period of 45–70 min after sunrise. We assume that the terrestrial vegetation represents the main rendezvous site and that searching flight leads to the majority of matings. One male was re- corded grasping a resting female. Wheel formation was completed while perching without further flight, resulting in a distinctive twisted wheel position. Further observations con- firmed that such twisted wheels found in the morning are typical. There are also records of occasional matings during the period from noon until late afternoon.
