My research has explored questions on the evolution of color signals, color vision, and flight morphology. I am particularly interested in understanding the evolution of color signals, how they are perceived by intended and unintended receivers and the role of these audiences in driving population and species divergence. I also study the evolution of flight morphology because wings are large conspicuous body surfaces that can be also used as motion signal vehicles for intra- and interspecific communication.

Knowledge and studies on the diversity of dragonflies in India is very high. Identification by traditional taxonomy often leads to misidentification. Incidence of sexual dimorphism is found to be high particularly in the Libellulidae and Aeshnidae family. In order to resolve the above mentioned problem, the accurate identification of the dragonflies was carried out by DNA barcoding using COI gene. In the present study, selected dragonfly species (Bradinopyga geminata, Crocothemis servilia, Diplacodes trivialis and Anaciaeschna jaspidea) of the family of Libellulidae and Aeshnidae were taken and along with three other evident species (Pantala flavescens, Orthetrum sabina, and Brachythemis contaminata) were retrieved from GenBank. The phylogenetic tree was created using NJ (Neighbour Joining) method to determine the origin and evolutionary relationships of the species. Similarity search was performed and conformed species were submitted to the NCBI and BOLD database for species authentication. The present study concluded that the DNA barcoding is an invaluable tool for the authentication of the species. Storage of this nucleotide information in a database like BOLD would greatly help in the identification up to sub species level.

Copyright (FAMIL K.A.Subramanian,Y 2005.: COENAGRIONIDAE) MARSH DARTS (FAMILY: COENAGRIONIDAE) Marsh darts are slender and small damselflies with varied colouration. These non-iridescent damselflies rest with wings closed over their body. The wings are transparent and rounded at the tip. The long and slender abdomen is slightly longer than the hind wing. Some of the smallest damselflies like the Golden Dartlet (Ischnura aurora) is from this family. Marsh Darts are found throughout the world. World over, this family is represented by about 1147 species. Within Indian limits, 65 species are known and in peninsular India 25 species are recorded. The marsh darts breed in a variety of aquatic habitats like ponds, marshes, streams and Photo:E.Kunhikrishnan rivers. Though most of the species are closely associated with aquatic habitats, some Golden Dartlets mating species like the Common Marsh Dart (Ceriagrion coromandelianum) can be found far away from any aquatic habitat.

  • The Damselfly and Dragonfly Watercolour Collection of Edmond
    International Journal of Odonatology, 2017 Vol. 20, No. 2, 79–112, https://doi.org/10.1080/13887890.2017.1330226 The damselfly and dragonfly watercolour collection of Edmond de Selys Longchamps: II Calopterygines, Cordulines, Gomphines and Aeschnines Karin Verspuia∗ and Marcel Th. Wasscherb aLingedijk 104, Tricht, the Netherlands; bMinstraat 15bis, Utrecht, the Netherlands (Received 3 March 2017; final version received 10 May 2017) In the nineteenth century Edmond de Selys Longchamps added watercolours, drawings and notes to his extensive collection of dragonfly and damselfly specimens. The majority of illustrations were exe- cuted by Selys and Guillaume Severin. The watercolour collection is currently part of the collection of the Royal Belgian Institute for Natural Sciences in Brussels. This previously unpublished material has now been scanned and is accessible on the website of this institute. This article presents the part of the collection concerning the following sous-familles according to Selys: Calopterygines (currently superfamilies Calopterygoidea and Epiophlebioidea), Cordulines (currently superfamily Libelluloidea), Gomphines (currently superfamily Petaluroidea, Gomphoidea, Cordulegastroidea and Aeshnoidea) and Aeschnines (currently superfamily Aeshnoidea). This part consists of 750 watercolours, 64 drawings and 285 text sheets. Characteristics and subject matter of the sheets with illustrations and text are pre- sented. The majority (92%) of all sheets with illustrations have been associated with current species names (Calopteryines 268, Cordulines 109, Gomphines 268 and Aeschnines 111). We hope the digital images and documentation stress the value of the watercolour collection of Selys and promote it as a source for odonate research. Keywords: Odonata; taxonomy; Severin; Zygoptera; Anisozygoptera; Anisoptera; watercolours; draw- ings; aquarelles Introduction The watercolour collection of Selys Edmond Michel de Selys Longchamps (1813–1900) did important work in odonate classifi- cation and taxonomy (Wasscher & Dumont, 2013; Verspui & Wasscher, 2016).

  • Dragonflies (Odonata) of Mulanje, Malawi
    IDF-Report 6 (2004): 23-29 23 Dragonflies (Odonata) of Mulanje, Malawi Klaas-Douwe B. Dijkstra Gortestraat 11, NL-2311 MS Leiden, The Netherlands, [email protected] Abstract 65 species of Odonata are recorded from Mulanje and its slopes. Only eight species dominate on the high plateau. Among them are two relict species of conservation concern: The endemic Oreocnemis phoenix (monotypic genus) and the restricted-range species Chlorolestes elegans. The absence of mountain marsh specialists on the plateau is noteworthy. Mulanje’s valleys, of which Likabula and Ruo are best known, have a rich dragonfly fauna. The Eastern Arc relict Nepogomphoides stuhlmanni is common here. Introduction Mulanje, at about 3000 m the highest peak between Kilimanjaro and Drakens- berg, is an isolated massif in Southern Malawi. From a plain at about 700 m altitude it rises almost vertically to a plateau with an average altitude of 2000 m. The plateau (including peaks) has a surface of about 220 km², being approxi- mately 24 km across at its widest point. The plain surrounding the massif was originally dominated by miombo (Brachystegia woodland), but is now largely under cultivation. The valleys are characterised by lowland and submontane forest, the plateau by montane forest, grasslands, bracken fields, scrub and rocky slopes, interspersed with countless streams (Dowsett-Lemaire 1988; Eastwood 1979). Surveys have shown that the Mulanje Massif contains over 30 million metric tonnes of bauxite, with an estimated excavation life of 43 years. In 2001 the government of Malawi announced to take action to exploit these reserves. Bauxite is an erosion mineral, which has been deposited superficially on the plateau.
