A biological and systematic study of the armored boreid, Caurinus dectes, with comparative notes on related mecoptera

Creator:: Russell, Loren Kenneth
Abstract:: Caurinus dectes Russell is a minute, brachypterous scorpionfly which was discovered at Marys Peak, Benton County, Oregon, in 1976, and subsequently described as the only representative of the subfamily Caurininae within the Boreidae (snow scorpionflies). Caurinus dectes is now known to range from the Olympic Peninsula and Northern Cascades in...

A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...

Biological studies on Saldula palustris (Douglas) with emphasis on factors influencing wing pigmentation (Heteroptera:Saldidae)

Creator:: Stock, Mary Wilford
Abstract:: The life history and wing pattern variation of the intertidal shore bug, Saldula palustris (Douglas), were studied in field and experimental populations from June 1970 until February 1972. The study site was an estuarine salt marsh on Yaquina Bay near Toledo, Oregon. The insects live below mean high water level...

Nearctic sawflies I, the adults and larvae of the subfamily Blennocampinae (Hymenoptera: Tenthredinidae)

Creator:: Smith, David R.
Abstract:: Seventy-two species of Blennocampinae in 21 genera and six tribes are known from the Nearctic region. The adults and known larvae of all species and genera are keyed, described and illistrated. A definition of the subfamily, a review of previous work, a table of host-plant associations, and a discussion of...

Revision of the genus Platylygus (Heteroptera: Miridae)

Creator:: Equihua-Martinez, Armando
Abstract:: The genus Platylygus Van Duzee was erected in 1915 and revised by Kelton and Knight in 1970 describing 26 new species from United State and Mexico. Despite this prior revision, taxonomic problems have been encountered with the use of the keys and in the identification given the close similarity among...

Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

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...

The morphology and biology of Macrovelia hornii Uhler (Heteroptera : Mesoveliidae)

Creator:: Anderson, Aage Bernard
Abstract:: The external and internal morphology are considered and important morphological characters are found which relate Macrovelis to the family Mesoveliidae. Both macropterous and Brachypterous forms occur throughout the western half of the United States. The adults and nymphs are restricted to the margins of springs and streams during the reproductive...
