The Florida Keys Mosquito Control District conducts adult mosquito surveillance by means of dry ice-baited light traps. Light traps have been used for nearly twenty years to monitor populations of adult mosquitoes. Trapping is done weekly except for interruptions due to storms, illness, or other unavoidable situations. Traps are provisioned with 2 pounds of dry ice and deployed in the late afternoon and retrieved the following morning. Traps are hung from the same tree limb each time except when trees have been uprooted due to storrms or human activity. Mosquitoes are taken to the laboratory, killed by freezing, and identified to species.

Deinocerites cancer Theobald is known as the "crabhole mosquito" mosquito due to its larval habitat, burrows of the land crab, Cardisoma guanhumi Latrielle. Adult female D. cancer take blood meals primarily from warm blooded animals, especially birds in the order Ciconiiformes (Tempelis and Galindo 1970). This species has been found infected with West Nile Virus (Hribar et al. 2003).

I thank all biologists and techicians who assisted with data collection and specimen identification during the past twenty years.
