  • diversity and ecosystem services of Trichoptera
    Insects, 2019
    Co-Authors: John C. Morse, Paul B Frandsen, Wolfram Graf, Jessica A Thomas
    Abstract:

    The holometabolous insect order Trichoptera (caddisflies) includes more known species than all of the other primarily aquatic orders of insects combined. They are distributed unevenly; with the greatest number and density occurring in the Oriental Biogeographic Region and the smallest in the East Palearctic. Ecosystem services provided by Trichoptera are also very diverse and include their essential roles in food webs, in biological monitoring of water quality, as food for fish and other predators (many of which are of human concern), and as engineers that stabilize gravel bed sediment. They are especially important in capturing and using a wide variety of nutrients in many forms, transforming them for use by other organisms in freshwaters and surrounding riparian areas. The general pattern of evolution for Trichopteran families is becoming clearer as more genes from more taxa are sequenced and as morphological characters are becoming understood in greater detail. This increasingly credible phylogeny provides a foundation for interpreting and hypothesizing the functional traits of this diverse order of freshwater organisms and for understanding the richness of the ecological services corresponding with those traits. Our research also is gaining insight into the timing of evolutionary diversification in the order. Correlations for the use of angiosperm plant material as food and case construction material by the earliest ancestors of infraorder Plenitentoria—by at least 175 Ma—may provide insight into the timing of the origin of angiosperms.

  • an amended checklist of the caddisflies of china insecta Trichoptera
    Zoosymposia, 2016
    Co-Authors: Lianfang Yang, Changhai Sun, John C. Morse
    Abstract:

    A new Chinese Trichoptera checklist includes 1267 described species in 116 genera and 30 families, each with a revised provincial distribution. Over the past 8 years, we have added 267 newly described species (or newly recorded species) to the Trichopteran fauna of China from the old checklist of 1000 species in 110 genera and 28 families (Yang et al . 2005), among which nearly 80 new species to the Chinese fauna were contributed by various foreign taxonomists. This checklist also reports six newly recorded species from China: Diplectrona obscura Ulmer, Diplectrona aurovittata (Ulmer), Hydropsyche boreas Malicky & Chantaramongkol, and Macrostemum hestia Malicky & Chantaramongkol of family Hydropsychidae; Adicella paludicola Ito & Kuhara of family Leptoceridae and Lannapsyche chantaramongkolae Malicky of family Odontoceridae. Psychomyia dactylina Sun 1997 is a synonym of Psychomyia martynovi Hwang 1957 and Chimarra bicuspidalis Sun 1998 is a synonym of Chimarra sadayu Malicky 1993. The species name of Cheumatopsyche pallida (Navas 1932) is a secondary junior homonym in the genus Cheumatopsyche , preoccupied by Cheumatopsyche pallida (Banks 1920). The new name for Ch. pallida will be published by Chang-hai Sun in a separate paper. Ecnomus orientalis Li & Morse 1997 is a junior primary homonym of E . danielae orientalis Gibon 1992 and is renamed E . anhuiensis , nomen novum . Apatania mirabilis Martynov 1909 is transferred to Apatidelia as Apatidelia mirabilis (Martynov 1909), new combination.

  • the Trichoptera world checklist
    Zoosymposia, 2011
    Co-Authors: John C. Morse
    Abstract:

    The Trichoptera World Checklist (TWC) is a project of the successive International Symposia on Trichoptera, with the responsibility for its policy and maintenance assigned to the international Trichoptera Checklist Coordinating Committee. The TWC originated 20 years ago and has been available on the worldwide web for over 11 years, providing ready access to data regarding caddisfly taxa. Security is assured by daily backup of the database. Trichoptera scientists everywhere are urged to continue sending their published research to the Editor. As of June 2009, the TWC included records for 13,574 valid, extant species and 308 valid, extant subspecies in 609 genera of 47 families. It also included 650 valid, extinct (fossil) species, 113 extinct genera, and 8 extinct families. The density of species among biogeographic regions is variable, with known species density in the Oriental Region about 7.5 times that in the Afrotropical Region.

  • chapter 257 Trichoptera caddisflies
    Encyclopedia of Insects (Second Edition), 2009
    Co-Authors: John C. Morse
    Abstract:

    Publisher Summary This chapter discusses the Trichoptera (Caddiflies), holometabolous insects closely related to Lepidoptera, or moths. Unlike most moths, their eggs, larvae, and pupae are usually found in or very near freshwater, and adults are aerial, usually not far from their aquatic habitats. The Trichoptera include more species than any of the other primarily aquatic orders of insects. This high species diversity is correlated with an unusual broad range of ecological specialization. Immature caddisflies occur in almost every type of freshwater habitat and on every continent except Antarctica; they are often one of the most abundant insect orders in streams and ponds. Larvae of many species use silk to construct portable cases of various shapes and materials to serve as physical protection, camouflage, or aids in respiration. Others make stationary retreats of silk for similar purposes or to serve as food-gathering structures. The variety of feeding strategies employed by caddisflies is as great as for the highly diverse freshwater Diptera, or true flies. Because of their diversity and density in most clean, freshwater ecosystems, the significance of caddisflies for processing nutrients and transferring energy is often great. The different caddisfly species are variously sensitive to changes in environmental conditions, such that the diversity of the order is commonly used in part as a measure of pollution.

  • new species of cheumatopsyche Trichoptera hydropsychidae from north sulawesi indonesia
    Pan-pacific Entomologist, 2008
    Co-Authors: Christy J Geraci, John C. Morse
    Abstract:

    Sulawesi Island has a high density of endemic animal species, including insects in the order Trichoptera. We describe the males of four new species of Cheumatopsyche (Trichoptera: Hydropsychidae) from North Sulawesi (Provinsi Sulawesi Utara), and provide a checklist of the Cheumatopsyche species from the Indonesian archipelago. Describing the aquatic insect fauna is an important step toward establishing biomonitoring protocols in Indonesia, which is experiencing rapid development and water pollution problems.

  • ephemeroptera plecoptera and Trichoptera assemblages from riffles in mountain streams of central brazil environmental factors influencing the distribution and abundance of immatures
    Brazilian Journal of Biology, 2006
    Co-Authors: Pitágoras Da Conceição Bispo, Leandro Goncalves Oliveira, Luis Mauricio Bini, K G Sousa
    Abstract:

    ABSTRACT The influence of environmental factors on the distribution of Ephemeroptera, Plecoptera and Trichoptera (EPT) immatures was investigated in streams of the Brazilian Center-West (Serra do Pireneus, Pirenopolis, State of Goias). The insects were sampled by lifting the stones in front of a sieve (0.5 mm mesh) and then removing the insects from both the stone and the sieve. Sampling was carried out for 1 h at 5 collection sites over a period of 14 months. Air and water temperature (°C), water velocity (m/s), discharge (m 3 /s), electric conductivity (µS/cm), pH, and rainfall (mm) were also recorded. In general, we may state that altitude, hydrologic classification (order) and vegetation cover were the most important factors explaining the distribution of Ephemeroptera, Plecoptera and Trichoptera immatures. The influence of the rainfall on the temporal variation of the abundance of insects was stronger in stream segments of medium order (3 rd , 4 th order) compared to smaller streams (first order).

  • Diversity of Hydropsychidae Curtis e Leptoceridae Leach (Insecta, Trichoptera) in streams of Parque Estadual Intervales, Serra de Paranapiacaba, Estado de São Paulo.
    Universidade de São Paulo, 2012
    Co-Authors: Rafael Alberto Moretto
    Abstract:

    A presente dissertação de mestrado resume-se a um estudo da diversidade de Leptoceridae e Hydropsychidae (Insecta, Trichoptera) do Parque Estadual Intervales, Estado de São Paulo, objetivando diminuir as lacunas distribucionais das espécies e facilitar o acesso de tais informações a outros pesquisadores, fornecendo subsídios taxonômicos para futuros trabalhos ecológicos ou de cunho conservacionista, aumentando assim, o conhecimento sobre as famílias Leptoceridae e Hydropsychidae e, consequentemente, sobre a ordem Trichoptera. A coleta foi realizada em dez riachos entre os meses de julho e agosto de 2010. O material coletado foi triado, preparado e identificado até o nível taxonômico de espécie. Análises quantitativas e testes estatísticos foram realizados para a determinação da riqueza e a abundância das duas famílias, além de, a partir das informações bióticas e abióticas nos diferentes riachos e das localidades de coleta, tentar inferir quais fatores ambientais são determinantes na distribuição faunística de tricópteros entre os diferentes riachos. Foi criada também uma checklist para as espécies de Leptoceridae e Hydropsychidae que ocorrem no Parque Estadual Intervales. Com a análise do material coletado, foi possível o reconhecimento de novas espécies e novos registros de espécies para o Estado de São Paulo. As novas espécies foram descritas ou encaminhadas para tricopterólogos especialistas, aumentando assim o conhecimento taxonômico do grupo em questão e contribuindo diretamente para a diminuição entre a diferença no número de espécies descritas na literatura e as estimativas do número de espécies existentes.This dissertation summarizes a study of the diversity of Leptoceridae and Hydropsychidae (Insecta, Trichoptera) in Parque Estadual Intervales streams, State of São Paulo, aiming to reduce the distributional gaps of species and facilitate the access of such information to other researchers, providing subsidies for future taxonomic or ecological studies and for nature conservation, and increasing the knowledge about the families Leptoceridae and Hydropsychidae and, consequently, of the order Trichoptera. Data were obtained between July and August 2010, when ten streams were sampled. The collected material was sorted, prepared and identified to the taxonomic level of species. Quantitative analysis and statistical tests were performed to determine the richness and abundance of the two families. Biotic and abiotic information from different streams and sampling localities were also analysed, trying to infer which environmental factors are determinant in the distribution of the fauna of caddisflies. A checklist of the species of Leptoceridae and Hydropsychidae from Parque Estadual Intervales is also presented. The analysis of the collected material showed the presence of new species; these were described or sent to experts, thus increasing the taxonomic knowledge of the Trichoptera and contributing to decrease the difference between the number of described species and estimates of the number of existing species

  • caddisflies Trichoptera from lombok bali and java indonesia with a discussion of wallace s line
    Deutsche Entomologische Zeitschrift, 2014
    Co-Authors: Hans Malicky, Vladimir D. Ivanov, Stanislav I Melnitsky
    Abstract:

    Abstract Caddisflies (Trichoptera) of Southeast Asia are analyzed with special attention to the Sun-da Islands to evaluate the zoogeographic effects of island isolation and potential influence from the neighboring continental faunas. Results of recent Trichoptera collections and synopsis of previously published data for the islands of Java, Bali, and Lombok are pre-sented along with their zoogeographical interpretation on the islands as well as on the adjacent regions. A total of 202 Trichoptera species is known to occur on the three islands; 146 species are known in Java, 73 in Bali and 61 in Lombok. 43 species are common to Java and Bali, 27 to Java and Lombok, 30 to Bali and Lombok, 70 to Java and Sumatra. A significant decrease in species richness has been observed in comparison to the Asian mainland. The caddisfly fauna of the three islands is of Asiatic origin, no Australian influ-ence was noted. The well-known Wallace’s line does not act as a faunistic border between Bali and Lombok for Trichoptera.

  • Identification of a Sex Pheromone Produced by Sternal Glands in Females of the Caddisfly Molanna angustata Curtis
    Journal of Chemical Ecology, 2008
    Co-Authors: Christer Löfstedt, Bill S. Hansson, Jan Bergmann, Wittko Francke, Erling Jirle, Vladimir D. Ivanov
    Abstract:

    In the caddisfly Molanna angustata , females produce a sex pheromone in glands with openings on the fifth sternite. Gas chromatographic analyses of pheromone gland extracts with electroantennographic detection revealed four major compounds that stimulated male antennae. These compounds were identified by means of gas chromatography–mass spectrometry and enantioselective gas chromatography as heptan-2-one, ( S )-heptan-2-ol, nonan-2-one, and ( S )-nonan-2-ol in the approximate ratio of 1:1:4:10, respectively. Field tests showed that the mixture of the two alcohols was attractive to males whereas addition of the corresponding ketones reduced trap catches. The sex pheromone of M. angustata , a species in the family Molannidae within the suborder Integripalpia, is similar to the pheromones or pheromone-like compounds previously reported from six other Trichopteran families, including members of the basal suborder Annulipalpia. This suggests that minimal evolutionary change of the pheromone chemistry has taken place within the leptoceroid branch of integripalpian Trichoptera compared to the ancestral character state.

  • global diversity of caddisflies Trichoptera insecta in freshwater
    Hydrobiologia, 2008
    Co-Authors: F C De Moor, Vladimir D. Ivanov
    Abstract:

    The not yet uploaded Trichoptera World Checklist (TWC) [http://entweb.clemson.edu/database/trichopt/search.htm], as at July 2006, recorded 12,627 species, 610 genera and 46 families of extant and in addition 488 species, 78 genera and 7 families of fossil Trichoptera. An analysis of the 2001 TWC list of present-day Trichoptera diversity at species, generic/subgeneric and family level along the selected Afrotropical, Neotropical, Australian, Oriental, Nearctic and Palaearctic (as a unit or assessed as Eastern and Western) regions reveals uneven distribution patterns. The Oriental and Neotropical are the two most species diverse with 47–77% of the species in widespread genera being recorded in these two regions. Five Trichoptera families comprise 55% of the world’s species and 19 families contain fewer than 30 species per family. Ten out of 620 genera contain 29% of the world’s known species. Considerable underestimates of Trichoptera diversity for certain regions are recognised. Historical processes in Trichoptera evolution dating back to the middle and late Triassic reveal that the major phylogenetic differentiation in Trichoptera had occurred during the Jurrasic and early Cretaceous. The breakup of Gondwana in the Cretaceous led to further isolation and diversification of Trichoptera. High species endemism is noted to be in tropical or mountainous regions correlated with humid or high rainfall conditions. Repetitive patterns of shared taxa between biogeographical regions suggest possible centres of origin, vicariant events or distribution routes. Related taxa associations between different regions suggest that an alternative biogeographical map reflecting Trichoptera distribution patterns different from the Wallace (The Geographical Distribution of Animals: With a Study of the Relations of Living and Extinct Faunas as Elucidating the Past Changes of the Earth’s Surface, Vol. 1, 503 pp., Vol. 2, 607 pp., Macmillan, London, 1876) proposed biogeography patterns should be considered. Anthropogenic development threatens biodiversity and the value of Trichoptera as important functional components of aquatic ecosystems, indicator species of deteriorating conditions and custodians of environmental protection are realised.
