Reproductive behavior of two Argia spp. (Odonata: Coenagrionidae) at an Arizona stream
Here we provide a first report on the reproductive behavior of Argia sabino Garrison and Argia pima Garrison from observations at Sabino Creek, Arizona. Both species reproduce in autumn (September-October) following late summer rainstorms. Tandem pairs of A. sabino submerge to oviposit on rock substrates. The oviposition substrate is abundant and widespread. Male A. sabino…
Distribution, habitat requirements and conservation of Macromia splendens Pictet (Odonata: Corduliidae) in Galicia (NW Spain)
The range of Macromia splendens, a rare anisopteran, includes SE France and some scattered localities on the Iberian Peninsula. During 1996-1998, I made an exhaustive search for the characteristics of the species’ larval and adult habitat, flight period and adult activity in NW Spain. Nine populations were found, greatly increasing its known range. Adults were…
The Odonata of Tunisia
Between 1987 and 1999 several visits to 69 localities in Tunisia were made. Altogether 46 species of Odonata, including 10 new to Tunisia, were recorded, raising the Tunisian checklist to 52 species. Our observations cover early May to mid June and late September to early November. Using as a basis for inference data from nearby…
The Odonata of Numidia, Northeaster Algeria Part II Seasonal ecology
This paper, a companion to Part I which treated status and distribution of Numidian Odonata, summarizes current knowledge of their seasonal ecology and identifies areas where promising research avenues exist. Annual patterns of adult occurrence and reproductive activity are used to infer life cycles, with particular reference to strategies that enable species to bridge the…
The Odonata of Numidia, Northeastern Algeria Part I Status and distribution
Forty-five species of Odonata have been recorded within Numidia, which includes the El Kala and the Guerbes-Senhadja wetlands in northeastern Algeria. Five species are new to the area. Changes occurring in dragonfly diversity over a century and a half are discussed. This paper (Part I) deals with the status and spatial distribution of each recorded…
The larva of Leucorrhinia patricia Walker (Odonata: Libellulidae)
The final-stadium larva of Leucorrhinia patricia Walker is described from six exuviae with associated teneral adults collected in northern British Columbia. L. patricia belongs to the group of nearctic Leucorrhinia that has larvae with three ventral stripes. The larvae are very similar to those L. hudsonica (Sélys) larvae that are small and lack dorsal spines….

On the biology of the damselfly Vestaus amabilis, Liefftinck (Odonata: Calopterygidae) in Borneo
The habitat, territorial and reproductive behaviour of the Bornean calopterygid damselfly Vestalis amabilis, are described. Males are territorial and will remain at the same site defending a territory for up to three weeks. Territories take the form of sun flecks whose physical location changes slowly throughout the day as the sun moves across the sky.
Sinocnemis yangbingi, gen. nov., sp. nov. and Sinocnemis dumonti, sp. nov., new platycnemidids from South-west China (Odonata: Plactycnemtoidae)
A new genus, Sinocnemis, gen. n., is established to receive two new species of platycnemidid described here as Sinocnemis yangbingi, sp. n., from Emeishan, Sichuan, China and Sinocnemis dumonti, sp. n. from Xishui, Guizhou, China.
New records of Crocothemis sanguinolenta (Burmeister, 1839) from Israel, with a critical note on the subspecies arabica, Schneider, 1982
Description of Gynacantha andamanae, spec. nov. from South Andaman Island, Indian Ocean (Anisoptera: Aeshnidae)
Gynacantha andamanae, [Yeh & Veenakumari] sp. nov. collected from Mt Harriet in South Andaman Island of Indian Ocean, is described and figured. The relationship of the new species with its oriental congeners is discussed.
The first recorded arrival of Anax junius, Drury (Anisoptera: Aeshnidae) in Europe: A scientist’s perspective
In September and October 1998 adults of Anax junius, (Common Green Darner) were encountered in small numbers at coastal sites in southwestern U.K. Circumstantial evidence supports the inference that they reached there on winds originating from New Brunswick and Quebec Canada in early September, a time when this species regularly migrates southwards along the Atlantic…
Interspecific encounters between male aeschnids do they have a function?
Male aeshnid dragonflies at a small pond (circumference ca 90 m) in Cambridgeshire U.K. generally pursued males of other aeshnid species as well as their own. As a result of these encounters the pursued insect frequently left the pond, particularly when it belonged to a smaller species. Libellulids, which differed greatly from the aeshnids in…
Additions to the knowledge of Sympetrum sinaiticum, Dumont (Odonata: Libellulidae)
New information shows that S. sinaiticum, is not divided into subspecies, as hitherto supposed. The subspecific name tarraconense, Jödicke, 1994 must be regarded as a junior synonym of sinaiticum., In contrast, the name arenicolor, Jödicke, 1994 denotes a taxon at full species rank, characterized by its larval and ligula morphology. This species is taxonomically identical…
Voltinism of Calopteryx haemorrhoidalis, (Vander Linden) in the Sierra Morena Mountains, Southern Spain (Zygoptera: Calopterygidae): A preliminary study
Small sweep-net samples of larvae of Calopteryx haemorrhoidalis, obtained during five consecutive years from a permanent stream in the Sierra Morena Mountains, southern Spain, were combined according to month to infer the voltinism during the study period. Detailed records of head width, wing-sheath length and metamorphosis status for individual larvae are consistent with the population…
A new subspecies of Gomphus (Gomphurus) septima from the Deleware River of New Jersey, New York, and Pennsylvania (Odonata, Gomphidae)
Gomphus (Gomphurus) septima delawarensis is described from the Delaware River, NJ, PA, and NY (Type locality: Flatbrookville, NJ). The new subpecies differs from nominate G septima septima Westfall (new status) mainly by differences in the male cerci and eplproct, and in the female vulvar lamina and lateral occipltal horns. The larvae of the two subspecies…
The response of larval growth rate to temperature in three species of coenagrionid dragonflies with some comments on Lestes disjunctus (Odonata: Coenagrionidae, Lestidae)
Larval growth rate has the same temperature coefficient in three species of coenagrionids, but Argia vivida and Amphiagrion abbreviatum, which frequently live in geothermally heated water, grow fastest at 29.0–30.0°C compared with 23.4°C for Coenagrion resolutum, which lives in cooler water. Survival below 15°C in the laboratory was much better in C. resolutum. These characteristics…
