摘要: The life histories, densities and distribution patterns of the most abundant macroinvertebrates, exclusive chironomids oligochaetes, are reported for a low-gradient, second-order, blackwater stream on Coastal Plain South Carolina, USA. Univoltine histories were found all species Coleoptera (Ancyronyx variegata, Macronychus glabratus, Dubiraphia quadrinotata Hydroporus clypealis) Ephemeroptera (Eurylophella temporalis, Paraleptophlebia volitans Hexagenia munda), although mayfly Stenonema modestum was at least bivoltine. Both univoltinism (Macrostemum carolina Pycnopsyche luculenta), partial bivoltinism (Nyctiophylax affinis) complete (Hydropsyche decalda, Cheumatopsyche sp., Phylocentropus placidus probably Chimarra florida) among Trichoptera. Odonate both univoltine (Calopteryx dimidiata, Enallagma divagans Epitheca cynosura) semivoltine (Boyeria vinosa, Gomphus lividus Macromia georgina). alderfly Sialis aequalis isopod Asellus laticaudatus univoltine, while blackfly Simulium taxodium produced 6 generations per year. Groups functionally-related within orders Odonata, Trichoptera each exhibited possible temporal and/or spatial segregation.
