A Survey for Stoneflies in the Homochitto National Forest, Southwest Mississippi

Streamside blacklight traps, aerial netting, and beating sheet samples of adult stoneflies were taken from streams of the Amite, Bayou Pierre, Buffalo and Homochitto River systems in the Homochitto National Forest of southwest Mississippi. Natchez (Alloperla natchez) and/or Chukcho (Haploperla chukcho) stoneflies, federal candidates for listing as threatened or endangered species, were found in 19 streams of the Homochitto River system, 3 streams of the Bayou Pierre system, and 1 stream of the Amite River system. Neither species was collected from tributaries of the Buffalo River. Occurrence of both species appears to be associated with stream order and canopy cover.
