  • Abundance and community composition of arboreal spiders : the relative importance of habitat structure, prey availability and competition

    Creator:
    Halaj, Juraj
    Abstract:
    This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed...

  • The taxonomic value of the metathoracic wing in the Scutelleridae (Hemiptera: Heteroptera)

    Creator:
    Au, Eunice Chizuru
    Abstract:
    Classification based on metathoracic wing venation does not coincide with the existing higher classification of the family Scutelleridae. The wings of the genera in the Scutellerinae possess a similar general pattern of venation which is quite distinct from that of Eurygasterinae, Odontoscelinae, Odontotarsinae, and Pachycorinae. The Scutellerinae wings possess three...

    Creator:
    Schwartz, Michael David
    Abstract:
    The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

  • Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

    Creator:
    Asquith, Adam
    Abstract:
    The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...
