ALDERFLY (NEUROPTERA: SIALIDAE) FLIGHT PERIODS, SEX RATIOS, AND HABITAT USE IN A VIRGINIA FRESHWATER TIDAL MARSH, LOW FOREST, AND THEIR ECOTONES
Barrows EM, McIntyre AM, Flint OS. 2005. ALDERFLY (NEUROPTERA: SIALIDAE) FLIGHT PERIODS, SEX RATIOS, AND HABITAT USE IN A VIRGINIA FRESHWATER TIDAL MARSH, LOW FOREST, AND THEIR ECOTONES. Proceedings of the Entomological Society of Washington. 107(3):693-699
This study concerns sialids. Six Malaise traps, run from April 1998 through December 1999, obtained 3306 adult Sialis iola Ross (34% females) and one male S. mohri Ross in Dyke Marsh Preserve (DMP), Virginia. They flew from early April through early June. The abundance of S. iola significantly varied among a low forest, freshwater tidal marsh, and the forest- marsh ecotone, sometimes being significantly more common in the ecotone than other habitats. Malaise traps can be used efficiently to survey and monitor sialids in DMP and similar places. A thorough monitoring effort in the Preserve should include at least two traps in the three habitats and monitoring throughout sialid flight periods and the Preserve.
