Description

Very neat coloration on this P. modestum - nearly perfectly matches the surroundings in the Hueco Tanks area, as shown in the photograph. Was only able to spot the individual as a result of seeing it move.

Found at indio mountain research station this cutie was found trying to be a rock. A team member watched as it ran past and was able to see where it stooped. These guys are incredible at blending in with patches of desert rocks. It was pretty bright and hot out this day, 26.6C.
