The Florida Keys Mosquito Control District deploys dry ice-baited light traps to monitor mosquito populations throughout the Florida Keys. Cross Key is an island directly north of Key Largo and via bridges it serves as a link between Key Largo and mainland Florida.

New information

This paper describes a data set compiled from trap collections on Cross Key, Florida, between September 23, 2002 and March 1, 2016.


Diptera, Culicidae, seasonal abundance, Cross Key, mosquito trap


The Florida Keys Mosquito Control District uses dry ice-baited light traps to conduct adult mosquito surveillance (Hribar 2002). Traps are deployed weekly except for interruptions due to storms, illness, or problematic situations. Each trap is provisioned with approximately 2 pounds of dry ice, deployed in the late afternoon, and retrieved the following morning. Traps are hung from the same tree limb every week unless trees have been uprooted due to storrms or cut down. Mosquitoes are treansported to the laboratory, killed by freezing, and identified to species.

General description


These data were collected to document the species composition, relative abundance, and seasonal distribution of mosquitoes (Diptera: Culicidae) on Cross Key.

Sampling methods

Study extent: 

The data presented herein were collected between September 2002 and March 2016 on Cross Key, an island north of Key Largo and south of mainland Florida. Data collection was attempted weekly although due to storms, illness, and vacation some weeks were missed.

Sampling description: 

Battery-powered light traps (American Biophysics Company, Clarke, John Hock) were provisioned with approximately two pounds of dry ice and hung from the same tree limb once weekly. Traps were set in the late afternoon and retreived the following morning. Trap catch was taken to the laboratory, frozen, and all mosquitoes separated, identified with the aid of Darsie and Morris 2003, and counted. Nonmosquito bycatch was examined ocassionally and reported elsewhere (Hribar 2020). Mosquito data were recorded in spreadsheets. Dates when no mosquitoes were collected are designated "No Mosquitoes" in the spreadsheet.

Red mangrove (Rhizophora mangle L.), black mangrove (Avicennia germinans L.), and buttonwood (Conocarpus erecta L.) comprise the majority of the flora at the site, with other typical marsh and hammock species present (Hribar 2002). Aedes taeniorhynchus (Wiedemann) and Anopheles atropos Dyar & Knab are the most commonly collected moquitoes at this site (DeMay and Hribar 2008).
