It fies among bushes and breeds in stagnant pools, small garden tanks, tubs and ornamental cement ponds containing submerged and/or foatng vegetaton. The ovipositon behaviour of C. coromandelianum was observed at the botanical garden of Hislop College, Nagpur, India, where small underground cement tubs are utlized to grow macrophytes. C. coromandelianum displays a refned hierarchy of preferences for ovipositon and chooses foatng leaves of Nymphaea nouchali (69%) over Lemna paucicostata (23%) and submerged Hydrilla vertcillata (8%). In an uninterrupted ovipositon bout, the female deposits 283 eggs in 16 rows (N=5) on the under surface of the N. nouchali leaf. The tny leaves of L. paucicostata holds 7.8 eggs in 4.8 rows (N=10). In H. vertcillata, the internode region of the stem can house 25.4 eggs (N=10). One or two eggs are also found neatly inserted in the thin leaf base of H. vertcillata. Decaying plant material is never used for ovipositon. The present investgaton also clearly demonstrates that the choice of ovipositon substrate not only depends upon the presence of aquatc species in the water body but also on the spatal locaton of the ovipositon site.

INTRODUCTION MATERIAL AND METHODS Habitat selecton for ovipositon is a vital and complex Site: The observaton and collecton for the present behavior undertaken by odonates, afer the terminaton work was carried out at the botanical garden of Hislop of copulaton. Ovipositon takes place either in water College, Nagpur, (21.160N & 79.030E) where small (aquatc), on foatng plant material (epiphytc), or inside underground cement tubs/tanks are used to grow plant tssue (endophytc). For damselfies, choice of macrophytes (Image 1). There is a large circular tub ovipositng material primarily depends upon “the inital (diameter 105cm) surrounded by six smaller circular tubs preference” which is a suitable place both, for landing (diameter 42cm), followed by a row of three rectangular and easy depositon of egg in the plant tssue (Waage cement containers (84cm x 47cm). Height of the tubs 1987; Martens 1992, 1993, 1994, 1996, 2001). Highly varies between two to three feet. Two rectangular stenotopic species oviposit in one or very few species tubs contain foatng L. paucicostata and submerged of plant while eurytopic species may exhibit distnct H. vertcillata while the small circular tubs contain preferences and oviposit in a wide variety of plants H. vertcillata.

    Sánchez-Herrera et al. BMC Evolutionary Biology (2020) 20:74 https://doi.org/10.1186/s12862-020-01638-z RESEARCH ARTICLE Open Access An exploration of the complex biogeographical history of the Neotropical banner-wing damselflies (Odonata: Polythoridae) Melissa Sánchez-Herrera1,2* , Christopher D. Beatty3, Renato Nunes2,4, Camilo Salazar1 and Jessica L. Ware2,5 Abstract Background: The New World Tropics has experienced a dynamic landscape across evolutionary history and harbors a high diversity of flora and fauna. While there are some studies addressing diversification in Neotropical vertebrates and plants, there is still a lack of knowledge in arthropods. Here we examine temporal and spatial diversification patterns in the damselfly family Polythoridae, which comprises seven genera with a total of 58 species distributed across much of Central and South America. Results: Our time-calibrated phylogeny for 48 species suggests that this family radiated during the late Eocene (~ 33 Ma), diversifying during the Miocene. As with other neotropical groups, the Most Recent Common Ancestor (MRCA) of most of the Polythoridae genera has a primary origin in the Northern Andes though the MRCA of at least one genus may have appeared in the Amazon Basin. Our molecular clock suggests correlations with some major geographical events, and our biogeographical modeling (with BioGeoBEARS and RASP) found a significant influence of the formation of the Pebas and Acre systems on the early diversification of these damselflies, though evidence for the influence of the rise of the different Andean ranges was mixed. Diversification rates have been uniform in all genera except one—Polythore—where a significant increase in the late Pliocene (~ 3 mya) may have been influenced by recent Andean uplift.

  • 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).

  • 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).
