The ecological energetics of the net-spinning caddisfly, Hydropsyche venularis Banks (Trichoptera: Hydropsychidae)
The study of organism level energetics in conjunction with ecosystem level energetics can lead to a better understanding of the structure and function of stream ecosystems. The purpose of this study was to calculate energy budget equations for a net-spinning caddisfly, Hydropsyche venularis Banks, …

Studies on the Odonata and Trichoptera of high-elevation lakes of northern Colorado and southern Wyoming
Freshwater biodiversity loss is a major concern, and global warming is already causing a significant role in species extinctions. The main goal of this research was to provide a baseline for specific aquatic insect species distributions at high-elevation lentic habitats in Northcentral Colorado and …

The ephemeroptera, plecoptera, and trichoptera of Missouri state parks with notes on biomonitoring, mesohabitat associations, and distribution
… and adult Ephemeroptera, Plecoptera, and Trichoptera (EPT) through 2002 and early 2003. All totaled, 34,251 EPT larvae were collected, all specimens of which were identified to the lowest taxon possible. Of approximately 70,000 adult specimens collected, 10,342 were identified to the …

Life history and growth of three populations of Glossosoma nigrior (Trichoptera: Glossosomatidae) from three thermally distinct locations
Three populations of Glossosoma nigrior Banks (Trichoptera: Glossosomatidae) were compared to determine how differences in thermal regime might affect their life history as well as the growth of individuals within each population. Two populations were located in Big Stony Creek (Stations 1 and 2) …

Contribuição ao estudo dos Trichoptera Kirby, 1813, na Represa dos Ciganos, Rio de Janeiro, baseada em larvas, pupas e casas (Insecta)
… old and the most important brazilian paper about Trichoptera written by MÜLLER (1880), these insects were only objects of foreign researchers, and the latest of them is FLINT, who estirnated (1981a) that only a third of brazilian imago caddisflies were described. There are about fourty cases and …

Life History and Case Building Behaviors of Phylloicus ornatus (Banks) (Trichoptera: Calamoceratidae) In Two Spring Fed Tributaries in the Central Edwards Plateau Bioregion of Texas
The life history and case-making behaviors of Phylloicus ornatus from two springfed first order streams in the Edwards Plateau Bioregion of Texas were studied from January 1998 to November 1999. Field larval, pupal and adult samples and laboratory rearings indicated a multivoltine cycle. First …

Submerged wood inhabiting macoinvertebrates of the Elm Fork of the Trinity River, Texas: Assemblage analyses, comparisons to the benthic fauna, and a study of Cyrnellus fraternus (Trichoptera: Polycentropodidae)
Taxonomic composition and spatio-temporal variability of macroinvertebrates inhabiting snags were examined from an 8-km segment of the Elm Fork of the Trinity River. Seventy-seven macroinvertebrate taxa were collected from submerged wood during the study. Assemblages were highly variable spatially …

An evaluation of the removal method for estimating benthic populations and diversity
… catch abilities included the case-building Trichoptera, the Mollusca, and the Annelida. The highest catch abilities were shown by the smaller Chironomidae and the nonburrowing Ephemeroptera. Taxa with high catchability generally showed high emigrability for Surber and Kicknet methods, …
