Deer tick - Dermacentor variabilis

Deer tick - Dermacentor variabilis
Wichita, Sedgwick County, Kansas, USA
April 27, 2006
Size: 15mm
I'm not sure what to call this fat and happy tick (well, maybe not so happy when I placed it on its back, but I uprighted it for the next image). I found it referenced in a book as both the "Blacklegged tick" - Ixodes scapularis and the "Deer tick" - Ixodes dammini, with the comment that it is called by both names. Is this a regional distinction? Or perhaps I've misidentified it altogether?

Moved from Deer Tick. Thanks Jon!

Dermacentor variabilis
Based on the first coxal spurs, shape of capitulum, and Y-shaped anal groove posterior to the anus, this is a D. variabilis rather than Ixodes scapularis.

Ixodes scapularis
this tick used to be called the black legged tick, but then i think after Lyme disease it was studied more and that it reproduced and lived on deer. they found that all the ticks in the genus Ixodes carry the virus and they split the old name, Ixodes dammini, to Ixodes scapularis, I. pacificus and a bunch others.

sorry i meant bacterium. Borrelia burgdorferi is a spirochete bacteria that is the causative agent of Lyme disease

Thank you...
...for your comments. I appreciate the information. Do you happen to know how long it takes for them to engorge to this degree?

more info
on Info page for Ixodes scapularis - the U. of Florida site in particular has lots of information

I clicked over... the U. of Florida page you recommended and found lots of interesting info. Thank you.
