This 2008 photograph depicted a dorsal view of a male, 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 symmetrical reticulated pattern, as in the case of this male tick, the scutum covers the entire dorsal abdominal surface. However, as you can plainly see in the case of the female (PHIL 10880), her scutum is much smaller, allowing for the expansion of her abdomen, which becomes engorged when ingesting her blood meal.
