This 2008 photograph depicted a dorsal view of a female, Amblyomma triste tick, as it was climbing a blade of grass. A neotropical tick, A. triste is a member of the Ixodides family of hard ticks, whose dorsal abdominal surface is covered by a hard, chitinous shell known as a scutum. Marked by a reticulated symmetrical pattern, the male tick (PHIL 10881) sports a scutum, which covers the entire dorsal abdominal surface. As you can plainly see in this case, the female’s scutum is much smaller, allowing for the expansion of her abdomen, which becomes engorged when ingesting her blood meal.
