Captured from a right anterior-oblique view, this 2005 photograph shows a close-up of a Culex tarsalis mosquito, resting on a piece of fabric. Note the light-colored band wrapped around its darkly-scaled proboscis (arrowhead), and though not noticeably apparent, if you look closely, the multiple, similarly light-colored bands wrapped around its distal appendages, i.e., the tibia and femur, characteristics that identify this as a C. tarsalis. The epidemiologic importance of C. tarsalis, lies in its ability to spread Western equine encephalitis (WEE), St. Louis encephalitis (SLE), and California encephalitis, and at the time of this image creation, was the main vector of West Nile virus (WNV) in the western United States.
