In a blacklight trap survey of Culicoides occurring in pastures selected from 3 of the 5 physiographic provinces of Virginia, the 5 most common species collected were C. biguttatus, C. obsoletus, C. stellifer, C. variipennis and C. venustus. Culicoides biguttatus was univoltine with a possible second emergence occurring in the coastal plain province. The other 4 species were multivoltine. Culicoides variipennis had the highest mean seasonal parous rates, being 73-83% during 1978 and 53-80% during 1979. The parous rate of C. biguttatus averaged 55% and C. obsoletus 8-45% during 1978 and 8-31% during 1979. Similar parous rates were observed in C. stellifer collected in 1978 (19-34%) and 1979 (4-30%).
