Scanning electron micrograph (SEM) of black salt marsh mosquito leg (femur) scales (Aedes taeniorhynchus). A. taeniorhynchus (also known as Culex taeniorhynchus) live and breed in salt marshes in coastal areas and occasionally in nearby freshwater pools. The adult female mosquito lays her eggs on the damp soil or associated with spike grass or salt meadow hay. When the tides are high, these areas flood, and the eggs hatch in to larvae. The adult is a strong flier and often migrates in large numbers to communities where they become serious pests, even many miles from the salt-water marshes. The black salt marsh mosquito is a severe biter of man and livestock along the southern coasts from North Carolina to Florida and in the Caribbean. It will blood feed on birds, mammals and humans. This mosquito that can transmit dog heartworms, Venezuelan equine encephalitis and West Nile Virus. Magnification: x265 when shortest axis printed at 25 millimetres.
