Description: Caption:
Under a low magnification of 23X, this scanning electron microscopic (SEM) image depicted a dorsal view of an unidentified male Dermacentor sp. tick found upon a cat in the suburbs of Decatur, Georgia, which measured approximately 3.5mm from its gnathosoma, which is where its mouthparts were located, to the distal abdominal margin. Note that the entire dorsum of this tick’s abdomen was covered by its tough scutum, or shield, categorizing it as a male, whereas, in female Ixodid-specie ticks, the scutum only partially covers the dorsal abdomen. The ridges running along the distal abdominal border are known as festoons.
