Abstract
The distribution of Culicoides (Diptera: Ceratopogonidae) in relation to plant cover in a North Carolina salt marsh was determined by sticky cylinder traps, emergence traps and soil sampling. All 3 methods showed essentially the same distribution pattern for C. hollensis (Melander & Brues) and C. furens (Poey) although the former was most abundant in tall (> 1.2 m) Spartina alterniflora Loiseleur (smooth cordgrass) and the latter in short (S. alterniflora. These 2 species were rare in the areas of juncus roemerianus Scheele (black needle rush) and shrubs. C. bermudensis Williams was not caught on sticky traps, but the other methods showed that this species was restricted to areas of Distichlis spicata (L.) Greene (salt grass) and J. roemerianus.
