A field study was conducted at Auburn, AL to compare the species of Culicoides midges attacking cattle in an open pasture and adjacent woodland from 1.5 hr before to 1.5 hr after sunset. Collections were made twice weekly from late April through October (50 trap nights) using drop-type closure traps baited with Holstein bulls. The same 13 Culicoides spp. were trapped at both sites, indicating no apparent difference in the species compositions in these two habitats. With one exception (C. arboricola which is typically ornithophilic), the number of each Culicoides sp. attracted to cattle in the open pasture was consistently greater (1.3-4.6 X) than the number of the same species taken on cattle in the bordering woods.
