Distribution expansion of Culex coronator in Alabama.

Culex coronator, a mosquito species common to the American tropics, has been recently documented from a number of temperate areas in the USA. Since 2002 specimens have been reported for the first time from Oklahoma, Louisiana, Mississippi, Alabama, and Florida. Here we provide new collection records for Cx. coronator in east-central Alabama. In October 2007, 2 larvae of Cx. coronator were collected from an artificial container in Tuskegee National Forest in Macon County, AL. The distribution of Cx. coronator in the USA seems to be expanding at a prodigious rate, for reasons that remain unclear.
