Revision, Description, And Diagnosis Of Adult And Larval Pycnopsyche Spp. (Trichoptera: Limnephilidae) Using Morphological And Molecular Methods, Matthew Green
All Dissertations
The genus Pycnopsyche Banks, 1905 (Trichoptera: Limnephilidae) is the 2nd most species-rich genus of Nearctic Limnephilidae. Larvae and adults are ecologically diverse and widespread throughout eastern North America. Larvae construct cases from mineral or plant material and are frequently used by biomonitoring professionals at the species level to monitor trends in water quality. However, only two species of Pycnopsyche are currently separable as larvae, with diagnosis limited by the number of unknown larvae associated with known adults. Using morphological and molecular data, the phylogenetic relationships among Pycnopsyche species and species groups were inferred with Bayesian and Maximum Likelihood analyses to …
Larval Taxonomy, Phylogeny And Historical Biogeography Of The Genus Cheumatopsyche (Trichoptera: Hydropsychidae) In North America, Zachary Burington
Larval Taxonomy, Phylogeny And Historical Biogeography Of The Genus Cheumatopsyche (Trichoptera: Hydropsychidae) In North America, Zachary Burington
All Theses
Larvae of the genus Cheumatopsyche (Trichoptera:Hydropsychidae) are a
abundant and probably significant ecological component of freshwater lotic ecosystems
worldwide, with many species inhabiting streams with elevated organic pollution. The
varying tolerance levels among these species necessitate species-level identification for
accurate water-quality assessment. However, past workers have had difficulty separating
the Nearctic species in the larval stage. This research presents progress on the goal
towards identification of larval Cheumatopsyche. Chaetotaxal and cuticular characters are delimited for 7 larval morphotypes, all of which have been putatively associated with
adults. The Nearctic phylogeny of Cheumatopsyche is revised, including 5 species
described after 1987. …
A Re-Examination Of Diplectrona Modesta Banks 1908 (Trichoptera: Hydropsychidae) Using Morphological And Molecular Techniques, Lauren Harvey
A Re-Examination Of Diplectrona Modesta Banks 1908 (Trichoptera: Hydropsychidae) Using Morphological And Molecular Techniques, Lauren Harvey
All Theses
Diplectrona modesta Banks 1908 (Trichoptera: Hydropsychidae) is a common inhabitant of streams across eastern North America. This species is well known and used often in biomonitoring studies. Experts in the field have long noted the morphological variation in larval head color and patterns as well as the species presence in many different types of habitats, such as springs, seeps, streams, and some small rivers. This study examines the species both morphologically and molecularly using mitochondrial and nuclear genes in order to determine if the species is a complex of several species or one highly variable species. DNA sequencing using the …
Six New Species And 1 New Species Record Of Orthotrichia (Trichoptera: Hydroptilidae) From China, Zhou Lei, Yang Lian-Fang, John C. Morse
Six New Species And 1 New Species Record Of Orthotrichia (Trichoptera: Hydroptilidae) From China, Zhou Lei, Yang Lian-Fang, John C. Morse
Publications
Six new species of the caddisfly genus Orthotrichia are described and illustrated from China, namely Or. apophysis Zhou & Yang, sp. nov.; Or. latiramifera Zhou & Yang, sp. nov.; Or. cornuta Zhou &Yang, sp. nov.; Or. discedata Zhou & Morse, sp. nov.; Or. cuspidigera Zhou & Yang, sp. nov.; and Or. subrhomba Zhou & Morse, sp. nov.. One species, Or. terpsichore Malicky & Chantaramongkol, 2007, is recorded for the first time from China, bringing the number of species of the genus known from China to 14. Of these, 10 species are distributed among 3 species groups of Marshall (1979), with …
Comparative Morphological And Functional Analysis Of Wing Coupling And Related Structures In Caddisflies (Insecta: Trichoptera), Ian Stocks
All Dissertations
Several orders of morphologically four-winged insects have evolved mechanisms that enforce a union between the mesothoracic and metathoracic wings (forewings and hindwings) during the wing beat cycle. Such mechanisms result in a morphologically tetrapterous insect flying as if it were functionally dipterous, and these mechanisms have been described for several insect orders. The caddisfly suborders Annulipalpia and Integripalpia (Trichoptera) have each evolved wing coupling apparati. At least three systems have evolved within the suborder Annulipalpia (Polycentropodidae; Hydropsychidae: Hydropsychinae, Macronematinae), and within Integripalpia the evolution of wing coupling mechanisms is diverse to the point that it defies simple enumeration into discrete …
Comparison Of Caddisfly Species (Insecta:Trichoptera) In The Northern Saluda Watershed Over A Thirty-Seven Year Period, In Correlation With Land Development And Use., Michael Biondi
All Theses
Land use and development in South Carolina has greatly increased in the last 50 years. This study focused on land cover change in Northern Pickens County and changes in caddisfly populations at three sites in three sub-watersheds in the South Saluda River watershed. I collected caddisflies from March 31 to October 20 in 2005 and 2006 and compared them to collections performed at the same sites in the same manner in 1969 by John C. Morse for his Master's thesis. I used a geographic information system to assess the land cover change over this thirty-seven year period and correlated the …
World Revision Of The Genus Triaenodes (Trichoptera: Leptoceridae), Junmi Hur
World Revision Of The Genus Triaenodes (Trichoptera: Leptoceridae), Junmi Hur
All Dissertations
One genus, Triaenodes of the long-horned caddisfly family Leptoceridae includes approximately 245 species globally and is cosmopolitan in distribution, occurring in all major faunal regions. The species of the genus, along with other species of caddisflies, are especially sensitive to pollution and are used by developed countries to monitor water quality.
Two hundred twenty-one species are reviewed and an additional 9 species are new to science. Twenty-six species groups are recognized in these subgenera of Triaenodes. The genus Triaenodes is divided here into seven monophyletic subgenera. The subgenus Ylodes Milne, 1934, has 15 species distributed in the Australasian, East …
Ceraclea Enodis, A New Species Of Sponge-Feeding Caddisfly (Trichoptera:Leptoceridae) Previously Misidentified, H Nicole Whitlock, John C. Morse
Ceraclea Enodis, A New Species Of Sponge-Feeding Caddisfly (Trichoptera:Leptoceridae) Previously Misidentified, H Nicole Whitlock, John C. Morse
Publications
A new species of Trichoptera, Ceraclea (C.) enodis, of the Ceraclea (C.) senilis Group, was discovered in freshwater sponge in the Little River in Montgomery County, North Carolina. Illustrations and descriptions of the male, female, larva, pupa, and larval case are given. Adults resemble those C. cancellata (Betten), the mature larva looks like that of C. maculata (Banks), the younger larva may be confused with C. transverasa (Hagen), and the pupa has anal rods rather like those of C. spngillovorax (Resh); but all life history forms can be distinguished reliably from these species by consistent morphological characters and the sponge …

Aquatic Insects Of Upper Three Runs Creek, Savannah River Plant, South Carolina. Part Iv: Caddisflies (Trichoptera) Of The Lower Reaches, Michael A. Floyd, John C. Morse, J Vaun Mcarthur
Publications
Ninety-three species of caddisflies, representing 14 families, were identified from collections obtained from two localities on Upper Three Runs Creek, Savannah River Site, Aiken County, South Carolina. Collections of adult caddisflies were made biweekly over a 1-yr period with ultraviolet light traps. The similarity index, Jaccard's Coefficient of Communities, showed that the two sites were over 78% similar with 73 species in common. Three species, Oxyethira setosa Denning, Triaenodes smithi Ross, and Nyctiophylax serratus Lago & Harris, are new distributional records for South Carolina. Two species of Triaenodes are new to science. Other species, which were considered to be endemic …
