Males and immature females can have stripes of red, yellow, and black on the abdomen. Ticks are larger than mites and are important because they are parasites of man and animals. The most prevalent tick in Arizona is the brown dog tick. It is specific to dogs and can develop infestations in kennels, backyards, and inside homes. This tick is not known to transmit human diseases.
Scorpions have two body regions, the cephalothorax and the abdomen.
The telson contains the stinger. Scorpions are active at night, feeding on insects such as cockroaches or house crickets. They are generally round in cross section and, with the exception of the first four or five, all of the body segments possess two pairs of legs. They are relatively slow moving, and feed on fungus and decaying plant material. At times, they can be a pest to vegetables or other plants in greenhouses.
