Adult Trichoptera were observed at the Plitvice Lakes, Croatia during two years (2000 and 2001) using pyramid-type emergence traps. A total of 1350 individuals and 37 species were collected. Throughout the study, the emergence patterns showed only minor variations regarding differences in particular habitats. During 2000 most species emerged in June, and in 2001 in May. The complete emergence period is shown for all collected species and studied in detail for abundant species. Excluding Allogamus uncatus, all abundant species emerged in summer, with most exhibiting a long emergence period. Rhyacophila fasciata had the longest emergence period in both years of the study and also showed winter activity. Trichopteran diversity and equitability were calculated and trophic relationships of the collected species were identified for each sampling site in order to obtain better insight into trichopteran community structure. Results indicated that the trichopteran community could be grouped according to travertine barriers and stream habitat types. IntroductionTo date, there have been various studies focusing on trichopteran communities in karst habitats, but mostly based on larval stages (e.g. BONADA et al., 2005;HABDIJA, 1988; HAB-DIJA et al., 2002). Besides, data of adult Trichoptera ecology and faunistics are commonly obtained by sampling with light and Malaise traps (e.g. SMITH et al., 2002;SVENSSON, 1974;WARINGER, 1991;. Thus emergence patterns and the length of the emergence periods are still insufficiently investigated for many species inhabiting karst areas.The emergence method has been used for various studies all over the world. At first, the method was used for quantitative production studies (ILLIES, 1971;MALICKY, 1976), but more recently it is mostly used for faunistic, phenological and biodiversity studies of running waters (FREITAG, 2004;FÜREDER et al., 2005;PETERSEN et al., 1999;WARINGER, 1996) due to its advantages over some other methods, e.g. benthos sampling (MALICKY, 2002). Hence, the emergence method was applied to investigate trichopteran community composition and emergence patterns in different karstic habitats.The Balkan Peninsula is known to be an important evolutionary centre for a number of trichopteran genera (e.g. Drusus, Rhyacophila, Tinodes, Potamophylax) resulting in a high species endemism (KUMANSKI and MALICKY, 1999). The Plitvice Lakes National Park was chosen for this study because of the presence of different habitat types typical of the karst systems (springs, streams, lakes and travertine barriers). Moreover, some endemic species from the mentioned genera inhabit the Plitvice Lakes area (KUČINIĆ and MALICKY, 2002;MARINKOVIĆ-GOSPODNETIĆ, 1971) and were thus encompassed in the study. The objectives of the study were (1) to define emergence patterns of species inhabiting karst but also to compare these with data from different habitats and regions (2) to investigate the composition, diversity and similarity of trichopteran fauna at different karst habitats, (3) to determine ...

“…Olinga species reproduce sexually and lay spherical egg masses comprising 100-300 eggs on a single occasion onto the water surface from where they settle on the streambed (Watson, 1974;Scarsbook, 2000). Adult life-span averages 3-4 days but can extend up to 8 days (Watson, 1974;Collier & Scarsbrook, 2000), and the flight period lasts between 3 and 5 months (Smith et al, 2002;Ward et al, 1996). While food and benthic habitat preferences are relatively well known (Lester et al, 1994;Parkyn & Winterbourn, 1997;Quinn et al, 2000), the life history and production of Olinga, particularly in relation to hyporheic habitat, are less well understood.…”

Life-history and production of Olinga feredayi in both benthic and hyporheic stream habitats were investigated in a pristine Waikato, New Zealand, forest stream over two years to investigate the contribution of hyporheic habitat to total secondary production. O. feredayi had a univoltine life-history with adult emergence occurring from November to March. Larvae with case lengths <2 mm were present on most dates suggesting delayed egg hatching. Benthic densities were inversely related to maximum peak daily flow in the month prior to sampling, and positively related to the dry mass of particulate organic matter present in samples. Reach-average benthic production calculated by the size-frequency method was 0.024 g DM m )2 year )1 . Hyporheic production was 4.276 g DM m )3 year )1 and 6.462 g DM m )3 year )1 in colonisation baskets set at 15-30 cm and 30-45 cm within the substratum, respectively, 2.3-3.4 times greater than production in surface baskets (0-15 cm). Averaged out over the reach scale, it was estimated that 96% of annual secondary production of O. feredayi occurred in hyporheic habitats > 10 cm below the streambed surface. Our study clearly demonstrates that only sampling benthic habitats can lead to gross under-estimation of population-level annual production, and provides evidence for the role of the hyporheos as a source of secondary production that may partly account for the Allen Paradox.

“…Individuals in these samples may have survived the entire dry period as adults, dispersed from perennial waters more than 700 m away in neighbouring catchments (Kovats et al 1996;Briers et al 2004;Winterbourn et al 2007), emerged from dry stream bed sediments, or undergone a period of adult dormancy (e.g. Sommerhauser et al 1997;Smith et al 2002).…”

Intermittent streams are predicted to harbour macroinvertebrate taxa with particular life history traits that allow them to complete development in a limited time and survive periods without water. Three intermittent headwater streams in Hawke's Bay, New Zealand, had more taxa with very small body size, plurivoltine life cycles, low dissemination potential, long-lived adults and asexual reproduction than three nearby perennial streams. We traced the population size structure and adult flight periods of six aquatic insect taxa, and the population size structure of an aquatic snail, in three intermittent streams to provide basic information on larval growth rates and infer whether they use particular life history stages to survive summer drought. The insect taxa appeared to over-summer primarily as eggs, whereas the snail Potamopyrgus antipodarum oversummered at various stages of maturity. Final instar larvae and adults of most insect taxa appeared well ahead of stream drying, suggesting they can survive early-onset drought. However, late-onset drought would allow more larvae to complete development.
