Magnified 95X, this scanning electron microscopic (SEM) image provided a closer view of this male Dermacentor sp. tick found upon a cat in the suburbs of Decatur, Georgia, which measured approximately 3.5mm from its gnathosoma (i.e., capitulum), which is where its mouthparts were located, to the distal abdominal margin (PHIL 9961). PHIL 9959 revealed all eight legs, placing the tick into the phylum Arthropoda, and the class Arachnida. From a proximal to a distal location, each leg is comprised of a coxa, trochanter-1, trochanter-2, a femur, patella, tibia, a two-sectioned tarsus, and a two-part pretarsus, i.e., a pulvillus and claw. Here we see the femur, patella, and tibia of the tick’s left 2nd and 3rd legs.
