  • First Record of Ceriagrion Fallax Ris (Odonata: Coenagrionidae) Preying on Small Web-Building Spiders (Arachnida: Tetragnathidae)
    International Journal of Odonatology, 2015 Vol. 18, No. 2, 153–156, http://dx.doi.org/10.1080/13887890.2015.1025244 First record of Ceriagrion fallax Ris (Odonata: Coenagrionidae) preying on small web-building spiders (Arachnida: Tetragnathidae) Xin Yu∗ Institute of Entomology, College of Life Sciences, Nankai University, Tianjin, PR China (Received 5 January 2015; accepted 28 February 2015) In montane forest of south-western Yunnan, China, a female of Ceriagrion fallax was observed and pho- tographed preying on a small web-building spider of the genus Leucauge. This is the first record of plucking an orb-weaver spider by a representative of the genus Ceriagrion. A brief discussion on the evolution of spider feeding behaviour in odonates is provided. Keywords: Odonata; Zygoptera; Coenagrionidae; Ceriagrion fallax; predation; Leucauge Introduction Many species of Odonata have been reported preying on small web-building spiders, as was related by Novelo-Gutiérrez and Ramírez (2013). After reading the interesting record of Novelo- Gutiérrez and Ramírez (2013), I recalled observing a similar event during my own fieldwork in which a little damselfly, Ceriagrion fallax Ris (Coenagrionidae), also caught a web-building spider as prey. Fortunately, I recorded the episode in detail in my fieldwork diary which I describe here. According to Dijkstra, Kalkman, Dow, Stokvis, and van Tol (2014), Ceriagrion is closely related to Telebasis (the temporary spider feeding specialist, according to Novelo-Gutiérrez & Ramírez, 2013) and pseudostigmatids (the obligatory spider feeding group). However there has so far been no report of Ceriagrion species preying on spiders. I suppose this observation should be a temporary specialization (Corbet, 1999).

  • The Superfamily Calopterygoidea in South China: Taxonomy and Distribution. Progress Report for 2009 Surveys Zhang Haomiao* *PH D
    International Dragonfly Fund - Report 26 (2010): 1-36 1 The Superfamily Calopterygoidea in South China: taxonomy and distribution. Progress Report for 2009 surveys Zhang Haomiao* *PH D student at the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou 510642, China. Email: [email protected] Introduction Three families in the superfamily Calopterygoidea occur in China, viz. the Calo- pterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese spe- cies has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the super- family in South China. In 2009, two series of surveys were conducted to Southwest China-Guizhou and Yunnan Provinces. The two provinces are characterized by karst limestone arranged in steep hills and intermontane basins. The climate is warm and the weather is frequently cloudy and rainy all year. This area is usually regarded as one of biodiversity “hotspot” in China (Xu & Wilkes, 2004). Many interesting species are recorded, the checklist and photos of these sur- veys are reported here. And the progress of the research on the superfamily Calopterygoidea is appended. Methods Odonata were recorded by the specimens collected and identified from pho- tographs. The working team includes only four people, the surveys to South- west China were completed by the author and the photographer, Mr.

  • Holistic Survey on Damselfly (Anisoptera : Odonata)Diversity in Rice Ecosystem of Eastern India
    International Research Journal of Natural Sciences Vol.4, No.4, pp.19-34, December 2016 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) HOLISTIC SURVEY ON DAMSELFLY (ANISOPTERA : ODONATA)DIVERSITY IN RICE ECOSYSTEM OF EASTERN INDIA C.R. Satpathi and A. Mondal Department of Agricultural Entomology Bidhan Chandra Krishi Viswavidyalaya( State agricultural University), P.O- Mohanpur, Dist. – Nadia, West Bengal -741252, India ABSTRACT: This study highlights the richness of Damselfly (Anisoptera: Odonata) fauna associated with rice ecosystems in Eastern India.. Sampling of the Damselfly community was conducted during 2010-14 to determine species composition, abundance and distribution in 3 different habitats of rice fields which were selected at 60 m (Chakdaha), 600 m (Cooch Behar) and 1250 m (Kalimpong) respectively. Each location was surveyed at a biweekly interval after transplanting of rice plants and about 10 species of Damselfly were recorded as insect predators in rice crops of Eastern India. General morphology, biology, ecology, behavior of the Damselfly are being highlighted in the present investigation. After comparing different body parts, double branching keys are prepared for their easy identification. The studies of their diversity showed that maximum and minimum value of both Simpson and Shannon-Weiner index were at the flowering and the vegetative stage of crop respectively. The value of Margalef index and Menhinck index also indicated that the highest value in reproductive stage of rice crop. The studies on Evenness index designated that the value of E1, E2 and E3 were influenced by species richness and not evenness. Consequently the influence of fertilizer on the incidence of Damselfly in rice ecosystem showed that there was a remarkable increase of population where high doses of nitrogen (120 kg/ha) were applied followed by the use of mix fertilizer(120:60:60 N:P:K).

    AES BIOFLUX Advances in Environmental Sciences - International Journal of the Bioflux Society Species richness of Odonata in Lanuza and San Agustin, Surigao del Sur, Philippines 1Samuel Jie C. Quisil, 1Jazzie D’zeim E. Arreza, 1Olga M. Nuñeza, and 2 Reagan T. Joseph Villanueva 1 Department of Biological Sciences, Mindanao State University - Iligan Institute of Technology, Iligan City, Philippines; 2 D3C Gahol Apartment, Davao City, Philippines. Corresponding author: S. J. C. Quisil, [email protected] Abstract. The Odonata spends its time in water and on land during its life cycle making this invertebrate an important link between aquatic and terrestrial ecosystems. To determine the species richness of Odonata in Lanuza and San Agustin, Surigao del Sur, assessment was conducted in 18 sampling sites in August to October 2012. Forty-nine species were documented where 26 species are under the suborder Zygoptera and 23 under suborder Anisoptera. Himatagan River of Lanuza, Surigao del Sur was found to be the most species-rich. Three species which are indicators of environmental disturbance were found to be abundant in eight sampling sites. These are the highly disturbed sites being in the vicinity of agroecosystems such as rice paddies, eggplant farms and root crop fields. Twenty-three Philippine endemic species were documented. Two species are new Mindanao record and one is endemic to the Philippines. More species are expected to be documented with intensive surveys especially in pristine habitats. Key Words: Anisoptera, indicator, invertebrate, river, Zygoptera. Introduction. Odonata, an order comprising Anisoptera (dragonflies) and Zygoptera (damselflies) (Arnett 2000), spends its time in water and on land during its life cycle making this order an important link between aquatic and terrestrial ecosystems (Kalkman et al 2008).
