An extensive larval mosquito survey was conducted in Craighead County in northeastern Arkansas in 1990-91. Nineteen species representing 8 genera were collected. Culex restuans was the most cosmopolitan species in relation to habitat utilization, being collected in 5 or 7 habitat types sampled. A major range extension of Aedes taeniorhynchus in Arkansas was documented as well as the first known collection of Aedes albopictus in the northeastern part of the state.
