Breve definición del grupo y principales caracteres diagnósticos Los tricópteros o frigáneas (Trichoptera, del griego trichos, "pelo" y pteron, "ala") son artrópodos de la Clase Insecta cuyos adultos portan alas cubiertas de pilosidad. Casi todas sus especies dependen del medio acuático para su desarrollo. La mayoría habitan en ríos y arroyos de aguas limpias y bien oxigena- das, aunque también se pueden encontrar en ambientes lénticos, terrestres e incluso marinos. Forman un grupo natural y están cercanamente emparentados con las mariposas y polillas (Lepi- doptera), que tienen escamas en sus alas y, como ellos, son capaces de producir seda. Ambos forman el superorden Amphiesmenoptera. De hecho, el grupo es sobre todo conocido por la habilidad de sus larvas para fabricar, con seda y diversos materiales, una gran variedad de construcciones como estuches portáti- les (Figura 1), refugios fijos, redes para la recogida de alimento y galerías, por lo que también se les ha denominado “arquitectos subacuáticos” (Mackay & Wiggins, 1979; Wiggins, 2004). Aunque para la cons- trucción de los estuches los tricópteros utilizan el material disponible en el lecho del río, el tipo y disposi- ción de las piezas que usan suele tener un marcado carácter filogenético (https://www.youtube.com/ watch?v=3vr6Z54LJtM&spfreload=10).

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

The checklist includes bibliographic research as well as results after reexamination of some specimens. For each species, we provide the taxonomic literature that examined Korean Trichoptera materials or mentioned significant taxonomic treatments regarding to Korean species. We also provide the records of unnamed species based on larval identification for further study. Based on taxonomic considerations, 20 species among the previously known nominal species in Korea are deleted or synonymized, and three species omitted from the previous lists, Hydropsyche athene Malicky and Chantaramongkol, 2000, H. simulata Mosely, 1942 and Helicopsyche coreana Mey, 1991 are newly added to the checklist. Hydropsyche formosana Ulmer, 1911 is recorded from the Korean Peninsula for the first time by the identification of Hydropsyche KD. In addition, we recognized 14 species of larvae separated with only tentative alphabetic designations. As a result, this new Korean Trichoptera checklist includes 218 currently recognized species in 66 genera and 25 families from the Korean Peninsula.

  • DBR Y W OREGON STATE
    The Distribution and Biology of the A. 15 Oregon Trichoptera PEE .1l(-.", DBR Y w OREGON STATE Technical Bulletin 134 AGRICULTURAL 11 EXPERIMENTI STATION Oregon State University Corvallis, Oregon INovember 1976 FOREWORD There are four major groups of insectswhoseimmature stages are almost all aquatic: the caddisflies (Trichoptera), the dragonflies and damselflies (Odonata), the mayflies (Ephemeroptera), and the stoneflies (Plecoptera). These groups are conspicuous and important elements in most freshwater habitats. There are about 7,000 described species of caddisflies known from the world, and about 1,200 of these are found in America north of Mexico. All play a significant ro'e in various aquatic ecosystems, some as carnivores and others as consumers of plant tissues. The latter group of species is an important converter of plant to animal biomass. Both groups provide food for fish, not only in larval but in pupal and adult stages as well. Experienced fishermen have long imitated these larvae and adults with a wide variety of flies and other artificial lures. It is not surprising, then, that the caddisflies have been studied in detail in many parts of the world, and Oregon, with its wide variety of aquatic habitats, is no exception. Any significant accumulation of these insects, including their various develop- mental stages (egg, larva, pupa, adult) requires the combined efforts of many people. Some collect, some describe new species or various life stages, and others concentrate on studying and describing the habits of one or more species. Gradually, a body of information accumulates about a group of insects for a particular region, but this information is often widely scattered and much effort is required to synthesize and collate the knowledge.

Montana Natural Heritage Program, Helena, MT. 83 pages. ii EXECUTIVE SUMMARY A variety of animal surveys were conducted during summer (May- September) 2012 as a baseline assessment of nongame wildlife on tribal lands on the Fort Peck Indian Reservation in northeastern Montana, the focus being all vertebrate groups (fish, amphibians, reptiles, birds, small mammals) and some aquatic invertebrate taxa (e.g. Mussels, Dragonflies) using relatively native habitats. Results of the surveys are intended to help guide stewardship and management of tribal lands as needs arise, whether they are in response to energy exploration and development, conflicts in land use practices, threats from invasive or non-native species, or other land management concerns. Of 72 total stream sites visited, fish were documented at 36 of 55 sites with water.
