Mouth parts of a lone star tick

The mouth parts of a lone star tick are revealed in vivid detail. The center of the mouth (yellow) is covered with many tiny barbs. These barbs keep the tick securely lodged inside the host while feeding. Lone star ticks are common in wooded areas throughout the central and eastern United States, including around Washington Dulles International Airport. They can carry disease-causing organisms, but these typically do not include the Lyme disease bacterium.
