    (excerpt) The subgenus Tipula (Tipula) is an Old World group with two introduced species in North America, the European Crane Fly, Tipula (T.) paludosa Meigen and T. (T.) oleracea Linnaeus, sometimes called the Common Crane Fly (Oosterbroek, 2005). Tipula paludosa is better known in North America, long established in the Pacific Northwest (Jackson 1975) and Canadian Maritimes provinces (Alexander 1962), more recently in California (Umble and Rao 2004, S. Gaimari, California Dept. Food and Agriculture, pers. comm.). It is a leading insect pest of turf grass and pastures in these areas, including infestin

    Wing interference patterns are consistent and sexually dimorphic in the four families of crane flies (Diptera, Tipuloidea)

    Wing interference patterns (WIP) are stable structural colors in insect wings caused by thin-film interference. This study seeks to establish WIP as a stable, sexually dimorphic, species-level character across the four families of Tipuloidea and investigate generic level WIP. Thirteen species of Tipuloidea were selected from museum specimens in the Academy of Natural Sciences of Drexel University collection. One wing from a male and female of each representative species was excised and mounted to a slide with coverslip, placed against a black background, and imaged using an integrated microscope camera. Images were minimally retouched but otherwise unchanged. Descriptions of the WIP for each sex of each species are provided. Twelve of thirteen species imaged had WIP, which were stable and species specific while eight of those twelve had sexually dimorphic WIP. Comparisons of three species of Nephrotoma were inconclusive regarding a generic level WIP. Gnophomyia tristissima had higher intraspecific variation than other species examined. This study confirms stable, species specific WIP in all four families of crane flies for the first time. More research must be done regarding generic-level stability of WIP in crane flies as well as the role sexual and natural selection play in the evolution of wing interference patterns in insects

    Review of East Palaearctic <I>Elliptera</I> (Diptera, Limoniidae) immatures with description of a new species

    The genus Elliptera Schiner, 1863 is represented by ten species worldwide, but immatures of only the European species E. omissa Schiner has been described so far. Molecular methods were used to associate larvae and adults for two East Asian species from South Korea. Elliptera jacoti Alexander and E. zipanguensis zipanguensis Alexander are common species in aquatic, hygropetric habitats in mountainous parts of the Korean peninsula. Elliptera mongolica Podeniene, Podenas &amp; Gelhaus sp. nov. from Mongolia and China (Inner Mongolia) is described based on mitochondrial DNA COI gene barcode sequences and morphological characters of larvae. Larvae of all three species and pupae of E. jacoti are described and illustrated. Morphological characters of the larvae useful for discrimination of species are given. An identification key for East Asian larvae of the genus Elliptera is compiled.</p

    Genitalic stridulation during copulation in a species of crane fly,Tipula (Bellardina) sp. (Diptera: Tipulidae)

    No full text
    The male genitalia of many animal groups have elaborate and species-specific forms. One hypothesis  to explain why this is so is that male genitalia function as stimulatory devices that are under sexual selection by cryptic female choice. This report is based on a videotaped observation of a single male of an unidentified species of Tipula (Bellarina) from San José Province, Costa Rica. A male crane fly stridulated (produced vibrations) during copulation using sustained and stereotyped movements of file and scraper structures on his genitalia. Males of related species have similar file and scraper structures on their genitalia, suggesting that they probably also stridulate during copulation. Rev. Biol. Trop. 57 (Suppl. 1): 251-256.

    Caloparyphus palaearcticus sp. n. is described from Russia and two localities in Mongolia and is the first representative of this genus in the Palaearctic and the only species found outside the New World. The morphological characters of the species are described and illustrated, and relationships to related species of Caloparyphus are discussed
