Tick - Amblyomma americanum
"The Lone Star Tick"
Males and Females
Note the ornate scutum with a central white mark on the female and the long mouth parts (the 2nd palpal segment is elongated). The eyes are on the lateral margin of the scutum.
It is widely distributed in the southern states east of the Rocky Mountains and in parts of Central and South America. The tick is most prevalent in spring and summer
A.americanum adults prefer large mammals like cattle, deer, horses and dogs
Immature stages usually attack birds and small mammals but may also be found on large mammals
Lone star ticks are frequently found on the ears, dewlap, escutcheon, and axillary and inguinal regions of livestock

Identification of a tick ...........
Ticks are the only members of the order Acarina that can be recognized without a microscope.
The most easily seen features are the spiracular plates (or stigmatal plates) which surround the external openings of the respiratory system. These plates are well developed and large.
They are located just outside the bases of the third and fourth pairs of legs.
Ticks feed only on the blood of vertebrates, making them one of the least favorite visitors in our homes. Hard ticks and soft ticks are the two major groups that are pests.
Hard ticks have the capitulum (where the head and mouthparts are located) exposed and easily visible from the top. The upper side of their body also bears a distinctly sclerotized shield or scutum.
This structure covers most of the upper body surface in the male tick, but is restricted to a much smaller area (immediately behind the capitulum) in the female.
When a female becomes completely engorged with blood, her abdomen increases to many times its normal dimensions and the scutum will then appear to be extremely small in relation to the body size. Male ticks do not become so large when engorged.
In soft ticks, the body has a rather non-descript sac-like shape. The front portion of the body extends forward, above and beyond the base of the capitulum, so that the capitulum is concealed when the tick is viewed from above.
Soft ticks of not have a scutum on the upper side of the body, and the exoskeleton is rather leathery in texture with a distinctly roughened surface.

Common Fowl Tick
Argas radiatus Raillet
This tick, known also as the chicken tick and the "blue bug," is a soft tick common in poultry houses in the southern and southwestern United States. It may injure or even kill chickens, and may attack humans. It can be controlled in chicken houses and bird-roosting areas by application of properly labeled insecticides such as Permethrin-10 concentrate or Permethrin Dust.
