Deer Tick? - Ixodes scapularis - female

Deer Tick? - Ixodes scapularis - Female
Milwaukee, Milwaukee County, Wisconsin, USA
October 29, 2007
Is this a female Ixodes scapularis? I found it on my arm after returning home from a walk in the woods. Can be frassed after ID confirmation.

Ixodes scapularis ("deer tick") - female
based on dark scutum (sclerotized plate) covering about half of dorsal surface whereas in the male it covers almost entire dorsum. This one frequently transmits Lyme disease plus rarely two other bad diseases, namely, Ehrlichiosis (= Human Granulocytic Anaplasmosis) and Babesiosis. It's disappointing that this individual latched onto you in Milwaukee County where I frequently do field work. I'm distressed to learn that in recent years deer ticks are becoming increasingly more abundant in Wisconsin counties bordering Lake Michigan. Here is evidence that late into Fall (October 29 and possibly after first frost?) is apparently not a safe period.

I had not seen any since I used to backpack the north Georgia mountains 20 years ago. Now, I'm seeing them regularily in Gulf Coast Alabama


 
Thanks for the ID confirmation
And more specifically, since you're familiar with the area, I picked this fellow up while walking in Schlitz Audubon Center.
