Western Black-legged Tick

== Description ==
Belonging to the family Ixodidae, the western black-legged tick is considered a slow-feeding hard tick which possesses a plated body armor. It is primarily found in the western region of the United States, particularly in northern California.
An adult male is around 1/10 of an inch, oval-shaped, and brownish-black in color. Due to the presence of a scutum on the dorsal side of the male, they are unable to feed in large quantities. Therefore, males of this species are unable to become engorged
An unfed adult female is around 1/8 of an inch in size, has a brown-black plate on the anterior back, an orange abdomen, and forward-projecting mouth-parts which enable feeding. While feeding, the adult female may engorge and expand to 3/8 of an inch or longer.
