The crane fly collection and a small amount of unidentified material deposited in the Zoo- logical museum, university of lund, Sweden, was examined by the author. Five species (Elephantomyia krivosheinae Savchenko, 1976, Erioptera nielseni de meijere, 1921, Go- nomyia subtenella Savchenko, 1972, Metalimnobia tenua Savchenko, 1976 and Tipula wahlgreni lackschewitz, 1925) are reported for the first time from Sweden. locality data for these species and nine other species, which are considered rare and poorly known in Sweden, is provided. layer photos of female hypopygium of Tipula wahlgreni and its close relative T. mutila Wahlgren, 1905 are presented.

A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Biological Sciences University of Alaska Fairbanks August 2017 APPROVED: Pat Doak, Committee Chair Greg Breed, Committee Member Colleen Handel, Committee Member Christa Mulder, Committee Member Kris Hundertmark, Chair Department o f Biology and Wildlife Paul Layer, Dean College o f Natural Science and Mathematics Michael Castellini, Dean of the Graduate School ABSTRACT Across the Arctic, taller woody shrubs, particularly willow (Salix spp.), birch (Betula spp.), and alder (Alnus spp.), have been expanding rapidly onto tundra. Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barcoding. We also created a generic identification key for crane flies of southern Brazilian salt marshes. We sampled crane flies continuously at three areas along the Patos Lagoon salt marshes over one year. A total of 14 genera/subgenera, 6 species, and 12 morphotypes belonging to Limoniidae and Tipulidae were identified. Distribution ranges ofSymplecta cana (Walker, 1848) and two Ormosia Rondani, 1856 species were expanded. mtDNA COI sequences were compared to the BOLD and NCBI databases, but were matched only at the family level. Therefore, we provided sequences to both platforms, updated to the genus level.

  • The Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats
    The Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] Version 1.1 26 November 2017 1 Summary This document provides a new checklist for the craneflies and winter gnats (Tipuloidea, Ptychopteridae and Trichoceridae) to extend the lists of the diptera of Lancashire and Cheshire first published by Kidd and Bindle in 1959. Overall statistics on recording activity are given by decade and hectad. Checklists are presented for each of the three Watsonian vice-counties 58, 59, and 60 detailing for each species the number of records, year of earliest and most recent record, and the number of hectads with records. A combined checklist showing distribution by the three vice-counties is also included, covering a total of 264 species, amounting to 75% of the current British checklist. Introduction This report is the third in a series to update and extend the partial checklist of the diptera of Lancashire and Cheshire published in 1959 by Leonard Kidd and Alan Brindle1. There were two previous updates, in 19642 and 19713. The previous reports in this series cover the soldierflies and allies4 and the Sepsidae5, the latter family not having been covered in Ref 1. The reader is referred to the first two reports for the background and rationale of these checklists, as well as the history of diptera recording and available data sources. The description of methodology is also kept to a minimum in the present report: only significant differences from the previous publications will be outlined.

Overgaard: Vertical distribution of insect populations in the free air space ofbeech woodland. Ent. Meddr 54: 169-178. Copenhagen, Denmark, 1987. ISSN 0013-8851. The vertical distribution of nocturnal aerial insect populations - especially Diptera Nematocera - in a high-holed beech stand was recorded by means of light traps placed at four levels from the forest floor to the top canopy. The insects were mainly trapped near the forest floor and to some extent in the beech canopy; the number recorded in the trunk space and above the top canopy was distinctly lower. In Tipulinae and Mycetophilidae, the vertical distribution declined with increasing height irrespective of season and weather; 80-85% of all specimens were recorded at ground level. In Limoniinae, Cecidomyiidae, Psychodidae and Sciaridae the vertical distribution pattern changed repeatedly during the season, being unimodal with a peak near the forest floor or bimodal with another one in the beech canopy.

Structure of the coxa and homeosis of legs in Nematocera Kiev-30, Ukraine 01601 (Insecta: Diptera). — Acta Zoologica (Stockholm) 85: 131–148 Construction of the middle and hind coxae was investigated in 95 species of Keywords: 30 nematoceran families. As a rule, the middle coxa contains a separate coxite, Insect locomotion – Homeotic mutations the mediocoxite, articulated to the sternal process. In most families, this coxite – Diptera – Nematocera is movably articulated to the eucoxite and to the distocoxite area; the coxa is Accepted for publication: radially split twice. Some groups are characterized by a single split. 1 July 2004 The coxa in flies is restricted in its rotation owing to a partial junction either between the meron and the pleurite or between the eucoxite and the meropleurite. Hence the coxa is fastened to the thorax not only by two pivots (to the pleural ridge and the sternal process), but at the junction named above. Rotation is impossible without deformations; the role of hinges between coxites is to absorb deformations. This adaptive principle is confirmed by physical modelling. Middle coxae of limoniid tribes Eriopterini and Molophilini are compact, constructed by the template of hind coxae. On the contrary, hind coxae in all families of Mycetophiloidea and in Psychodidae s.l. are constructed like middle ones, with the separate mediocoxite, centrally suspended at the sternal process. These cases are considered as homeotic mutations, substituting one structure with a no less efficient one.
