The spatial and temporal distribution of 28 species of female mosquitoes resting in natural (swamp, woods, and swamp-woods ecotone) and human-made (beneath bridges) habitats in blackwater stream-associated ecosystems in Duplin County, N.C., was determined by sampling with a D-Vac vacuum aspirator during 1984 and 1985. Two types of resting distributions were evident. In type one, species including Aedes atlanticus Dyar & Knab, Ae. canadensis (Theobald), Ae. triseriatus (Say), and Psorophora ferox (von Humboldt) rested predominantly on vegetation and were not collected beneath bridges. In type two, species including Anopheles punctipennis (Say), Culex erraticus (Dyar & Knab), Cx. peccator Dyar & Knab, Cx. pipiens L. and Cx. quinquefasciatus Say and their hybrids, Cx. restuans Theobald, Cx. territans Walker, and Uranotaenia sapphirina (Osten Sacken) rested on vegetation, in natural shelters in swamp habitats, and beneath bridges. Differences in the proportion of gravid mosquitoes among habitats were evident for Ae. canadensis, An. punctipennis, Cx. pipiens and Cx. quinquefasciatus and their hybrids, Cx. restuans, Cx. territans, Ps. ferox, and Ur. sapphirina, indicating that gonotrophic condition may influence resting site selection.
1984年和1985年期间，通过使用D-Vac真空吸虫器进行采样，确定了北卡罗来纳州达普林县黑水溪流相关生态系统中自然（沼泽、树林和沼泽-树林交错带）和人造（桥下）栖息地中28种雌性蚊子的时空分布。明显存在两种类型的栖息分布。在第一种类型中，包括大西洋伊蚊Dyar & Knab、加拿大伊蚊（Theobald）、三带喙库蚊（Say）和凶猛脉毛蚊（von Humboldt）在内的物种主要栖息在植被上，未在桥下采集到。在第二种类型中，包括尖音库蚊（Say）、迷走库蚊（Dyar & Knab）、佩氏库蚊Dyar & Knab、致倦库蚊L.和致倦库蚊Say及其杂交种、雷氏库蚊Theobald、环跗库蚊Walker和天蓝伊蚊（Osten Sacken）在内的物种栖息在植被上、沼泽栖息地的自然庇护所中以及桥下。对于加拿大伊蚊、尖音库蚊、致倦库蚊及其杂交种、雷氏库蚊、环跗库蚊、凶猛脉毛蚊和天蓝伊蚊，不同栖息地中孕蚊比例存在明显差异，这表明生殖营养状况可能影响栖息场所的选择。
