Aquatic insects were collected from 18 sites in the Yongsan River System from August, 1988 to July, 1989. The monthly fluctuation and distributional pattern of the aquatic insects along the environmental factors were investigated. Quantitatively collected aquatic insects were identified, and numbers, standing biomass, dominance indices and diversity indices in each site and month were determined. The aquatic insect faun of the Yongsan River System was composed of 146 species, 82 genera, 38 families in 7 orders including 44 species of mayflies, 32 species of caddisflies, 24 species of stoneflies, 21 species of flies, 16 species of beetles, 6 species of dragonflies and 3 species of dobsonflies. Seasonal occurrence of species were more diversified in winter and spring than in summer. Also, the number of individuals occurred was higher in winter and spring than in summer while it was the highest in upper stream and the lowest in Kwang-ju stream. Component ratio of the number of individuals according to the insect orders was as follows: Mayflies 38.71%, Flies 36.97%, Stoneflies 10.21%, Caddisflies 6.80%, Beetles 2.96%, Dobbsonflies 2.74%, Dragonflies 0.95%. Percentage of standing biomass according to insect orders were as follows: Mayfiles 32.81%, Stoneflies 26.51%, Caddisflies 17.58%, Dobbsonflies 14.84%, Flies 3.74%, Beetles 3.08%, Dragonflies 1.45%, The highest standing biomass occurred in spring and the lowest in summer.

Trichoptera, or caddisflies, comprise one of the major aquatic insect orders. Like Lepidoptera, caddisflies are capable of spinning silk from specially modified salivary glands, and the diversity of ways this silk is used probably accounts for the success of the order as a whole. These utilize silk to construct both larval and pupal shelters, often incorporating materials from the environmental among the silk thread. In this study, we try to find and characterize novel type genes that should be translated to major component protein of aquatic silk. (omitted)

Adult caddisflies were collected from 11 sites in Cheongdo-gun (Gyeongsangbuk-do) and Miryang-si (Gyeongsangnam-do) in the southeastern part of the Korean Peninsula. Collections on August 28 to 30, 2015, by aerial sweeping and light trapping, included one new species and four newly recorded species from the Korean Peninsula. Description of the new species Paduniella unmun Inaba and Park (Psychomyiidae), and re-description of the four species (Polyplectropus malickyi Nozaki et al., 2010, Tinodes furcatus Li and Morse, 1997, Cheumatopsyche tanidai $Ol{\acute{a}}h$ and Johanson, 2008, and Diplectrona kibuneana Tsuda, 1940) are provided. Additionally, we recognize that a larva described as Diplectrona KUa is the larval stage of D. kibuneana.

An examination of caddisfly materials from the field trips in Vietnam during 2002-2003 resulted in the recognition of the male adult of Tinodes reuse Malicky & Chantaramongkol(new Vietnamese record) and four undetermined species of larvae (Psychomyia VL1, Psychomyia VL2, Paduniella VL1, and Tinodes VL1) in the family Psychomyiidae Genera Psychomyia and Paduniella are recorded from Vietnam for the first time. Material data, descriptions, diagnoses, distributions, and taxonomic remarks are provided.

A revised checklist of Korean Trichoptera is provided for the species recorded from the Korean Peninsula, including both North and South Korea. 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.

The specimens of caddisflies previously recorded as Sortosa distincta (Walker, 1852), Rhyacophila uchidai Kobayashi, 1989, Rhyacophila jirisana Kobayashi, 1989, Crunobiodes koriaensis Kobayashi, 1989, and Ganonema odaenum Kobayashi, 1989 from South Korea were reexamined. Rhyacophila uchidai and R. jirisana are newly synonymized with R. retracta Martynov, 1914 and R. vicina Botosaneanu, 1970, respectively. We reconfirm two synonyms, C. koriaensis with Lepidostoma sinuatum (Martynov, 1935) and G. odaenum with Psilotreta locumtenens Botosaneanu, 1970, and a misidentification of Dolophilodes affinis Levanidova and Arefina, 1996 as S. distincta. Some specimens recorded as G. odaenum are identified as Psilotreta falcula Botosaneanu, 1970.

Since a large bank-protection works project was undertaken during winter in the middle reaches of the Chikuma, the riverbed structure was drastically altered. In order to assess the short-term impact of bank-protection works on the abundance Pattern of Stenopsyche marmorata (Trichoptera) from spring to early summer, we conducted an investigation on the capture of adults using light traps before and after construction work. The patterns of the daily capture of S. marmorata and the Namely, after construction, the daily catch of adult numbers increased only slightly during the investigation periods. This suggested that the age structure of the S. marmorata larval population had changed in the construction area. Our data suggest that bank-protection projects impact the abundance pattern of adult caddisflies in the river ecosystem.

Benthic macroinvertebrate communities were studied after a small dam removal from the mid-section of the Gyeongan stream in Gyeonggi-do, Korea. Quantitative sampling was conducted at immediately upstream (upper) and downstream (lower) sites from the dam as well as at the site where the dam was located (dam site: middle) using a Surber sampler (50$\times$50 cm, mesh 0.25 mm), four times (November 2004, May 2005, January 2006, and May 2006) after the dam removal. As a result, 46 species of benthic macroinvertebtates, belonged in 35 genera, 27 families, 11 orders, 5 classes, and 4 phyla, were sampled from the stream sites, but the number of species that occurred at each sampling trial was different (ranged 3$\sim$17 spp.) according to the seasons and sites. Approximately one year after the dam removal, the species number has in-creased and taxa composition has changed as the microhabitat became more heterogeneously due to a riffle formation in the upstream site. Chironomid larvae and tubificid worms, which are common in Korean urban streams, were the dominant species, while Hydropsyche kozhantschikovi was the 2nd dominant species at some sampling trials. In general, McNaughton's dominance indices decreased and Shannon species diversity indices increased approximately one year after the dam removal. Compositions of collector-filterers, clingers, and swimmers increased as hydropsychid caddisflies, heptageniid mayflies, and baetid mayflies increased, respectively, in the upstream site. The group pollution index and the ecological score using benthic macroinvertebrates both indicated that water environment has been improved in the upstream site after the dam removal.
