I was asked me the significance is of the white spot on nasty little tick that Edward Cullen'd me back in Tennessee. The spot is how the tick can be identified a 'Lone Star tick', one of the tick species carrying Lyme Disease.
When I looked up the tick's ID on line, I almost fell over! The little bugger is the same species of little $%&# that sucked my blood back in 1998 when I birded at Aransas National Wildlife Refuge in Texas. So this was a repeat tick for me. That's the actual tick that rode around in my drawers in Arkansas - *shudder*.
Here's a life time's supply of tick info HERE.
