Life-History Study of Libellula Incesta with Emphasis on Egg Development As Influenced by Controlled Temperature (1971) Directed By: Dr
PITTMAN, ANNETTE ROGERS. Life-History Study of Libellula incesta with Emphasis on Egg Development as Influenced by Controlled Temperature (1971) Directed by: Dr. Paul E. Lutz. pp. 75. A field and laboratory study was carried out with Libellula incesta to investigate the effects of controlled temperature and photoperiod on egg development and to determine various aspects of the life cycle. Eggs collected from mating females were subjected to two photoperiods (11 and 14 hours) at each of six different temperatures (15, 20, 25, 30, 35, and 40°C). Libellula incesta eggs were not effected by difference in photoperiods, but total development time decreased with increases in temperature. Information concerning the life-history was obtained by sampling the larval population and field observation throughout the year. It was established that the eggs of Libellula incesta experienced direct development in about one to two weeks. In addition it was found that Libellula incesta is a univoltine summer species which overwinters in one of four instars prior to the final. Emergence began in mid-May and individuals flew until mid-October. Throughout this flight season the reproductive activity was observed. Males established territories in which they interacted with other males and mated with females. The females frequented the water only to mate and to exophytically oviposit large quantities of eggs.

Bramshill Site of Special Scientific Interest
The Dragonflies of Bramshill Site of Special Scientific Interest Freshwater Habitats Trust Author Ken Crick Forward Bramshill Site of Special Scientific Interest (SSSI) is a Flagship Pond Site. Part of a network of the very best of Britain’s ponds; sites of exceptional importance for freshwater wildlife and some of our finest freshwater habitats. The Flagship sites can be a single special pond, or more commonly group of ponds, selected because they support rich, often irreplaceable, communities and species at risk of extinction. They represent some of the least impacted, most diverse pond habitats remaining in the country. Many of our nation’s most beautiful and biodiverse waterbodies have degraded irrevocably, and it’s critically important that the remaining sites are well protected and well managed. In 2015, with funding from the Heritage Lottery Fund, Freshwater Habitats Trust launched the Flagship Ponds project, Mats of Water Crowfoot flower on Bramshill working with land managers and community groups to ensure that the most Plantation’s Longwater. critical pond sites in Britain were protected for the long term. This book has been published with the aim of enabling people visiting this, Introduction immensely important Flagship Pond Site in Northern Hampshire, to identify the dragonflies and damselflies they encounter - by reference to a simple text This nationally important Site of managed by Forestry Commission and in places subsequent backfilling Special Scientific Interest (SSSI) England (FCE), please see the site with landfill, Bramshill SSSI has and photographs.

Matthias Dehling2, Roland Brandl1 and Martin Brändle1* 1Department of Ecology – Animal Ecology, ABSTRACT Faculty of Biology, Philipps-Universität Aim We compared the effects of recent shifts of northern range boundaries of Marburg, Marburg, Germany, 2Biodiversity and Climate Research Centre (BiK-F) and odonates adapted to either lentic (standing water) or lotic (running water) habitats Senckenberg Gesellschaft für Naturforschung, in Europe. Lentic species are thought to have a higher dispersal propensity than Frankfurt (Main), Germany, 3Center for lotic species because of the lower spatial and temporal persistence of lentic habitats Macroecology, Evolution and Climate, on average. Hence, we expected shifts in the range boundaries particularly of lentic Department of Biology, University of species. Copenhagen, Copenhagen, Denmark Location Europe. Methods Our analyses are based on odonate distribution maps from two field guides that present the European ranges of dragonflies and damselflies in 1988 and 2006. We categorized species according to their preference for lentic or lotic habi- tats, and then assigned each species to a southern or a northern group according to the centre of its distribution. Shifts in northern range boundaries were calculated as the average distance between the 10 northernmost grid cells in 1988 and 2006. Range boundary shifts were also analysed with regard to prevalence, phenology, body size and wing size. Results Lentic species of the southern group expanded their range boundaries on average 115 km northwards per decade, whereas lotic species of the southern group on average did not change their range boundaries. -

An Anomalous Connection in the Genus Aeshna Fabricius, 1775 (Odonata: Aeshnidae) with an Additional Record of Aeshna Cyanea (Müller, 1764) from Turkish Thrace
Acta entomologica serbica, 2010, 15(1): 1-6 UDC 595.733(560) AN ANOMALOUS CONNECTION IN THE GENUS AESHNA FABRICIUS, 1775 (ODONATA: AESHNIDAE) WITH AN ADDITIONAL RECORD OF AESHNA CYANEA (MÜLLER, 1764) FROM TURKISH THRACE NURTEN HACET Trakya University, Faculty of Arts and Sciences, Department of Biology, TR-22030 Edirne, Turkey E-mail: [email protected] Abstract A heterospecific tandem between a male Aeshna affinis Vander Linden, 1820 and a female Aeshna cyanea (Müller, 1764) is reported from İğneada (Longos Forest) in Kırklareli province in the Turkish Thrace Region. The locality, where the tandem was observed, is the second recording locality for A. cyanea from the region. KEY WORDS: Odonata, dragonfly, heterospecific tandem, Aeshnidae, Aeshna, Turkish Thrace, Turkey Introduction Recent studies have indicated that heterospecific tandems within Odonata are not unusual (BICK & BICK, 1981; UTZERI & BELFIORE, 1990; CORBET, 1999). However, the difficulty in detection of females in heterospecific pairs for some genera restricts the number of records of such pairs (BICK & BICK, 1981; CORBET, 1999). Thus, it is probable that there are unreported or unpublished records of heterospecific pairs among dragonflies, and it is possible that the total number of all records is greater than the amount of available data. Heterosexual heterospecific tandems were recorded and observed more often in Anisoptera than Zygoptera, and most of the known records showed that heterospecific pairs consist of individuals of the same genus (CORBET, 1999). Aeshnidae from Anisoptera is one of the families for which heterospecific pairings were recorded, and Sympetrum and Gomphus are Anisopteran genera including the highest record numbers of mixed pairings (BICK & BICK, 1981; CORBET, 1999). -
Glossary - Zoology - Intro
1 Glossary - Zoology - Intro Abdomen: Posterior part of an arthropoda’ body; in vertebrates: abdomen between thorax and pelvic girdle. Acoelous: See coelom. Amixia: A restriction that prevents general intercrossing in a species leading to inbreeding. Anabiosis: Resuscitation after apparent death. Archenteron: See coelom. Aulotomy: Capacity of separating a limb; followed by regeneration; used also for asexual reproduction; see also fissipary (in echinodermata and platyhelminthes). Basal Lamina: Basal plate of developing neural tube; the noncellular, collagenous layer that separates an epithelium from an underlying layer of tissue; also basal membrane. Benthic: Organisms that live on ocean bottoms. Blastocoel: See coelom. Blastula: Stage of embryonic development, at / near the end of cleavage, preceding gastrulation; generally consisting of a hollow ball of cells (coeloblastula); if no blastoceol is present it is termed stereoblastulae (arise from isolecithal and moderately telolecithal ova); in meroblastic cleavage (only the upper part of the zygote is divided), the blastula consists of a disc of cells lying on top of the yolk mass; the blastocoel is reduced to the space separating the cells from the yolk mass. Blastoporus: The opening into the archenteron (the primitive gastric cavity of the gastrula = gastrocoel) developed by the invagination of the blastula = protostoma. Cephalisation: (Gk. kephale, little head) A type of animal body plan or organization in which one end contains a nerve-rich region and functions as a head. Cilium: (pl. cilia, long eyelash) A short, centriole-based, hairlike organelle: Rows of cilia propel certain protista. Cilia also aid the movement of substances across epithelial surfaces of animal cells. Cleavage: The zygote undergoes a series of rapid, synchronous mitotic divisions; results in a ball of many cells.
