Identification?
Bonus points if you can tell what is going on with this tick (hint, it's a rarely-captured stage of the life cycle).

Case of the Week 384
We're on a roll with arthropods! This week's case was donated by Dr. Ellen Stromdahl. This arthropod was removed from a patient and sent to her lab for analysis. It was beautifully photographed by Graham Snodgrass.

Without a scale, it's hard to say exactly what stage of this Ambloyomma (Lone Star) tick we're seeing.
The Lone Star tick, Amblyomma americanum. Is it molting?

It's a female Amblyoma americanum, by the marking on the small scutum and mouth parts.

Lone star tick (Amblyomma americanum)nymph about to molt/molting to an adult female? I see the ornate spot on the scutum which suggests an adult female of this species, but it looks like there is some sort of integument covering the tick.
As mentioned earlier, a scale would be needed as well as closer inspection to make a better determination. Where and when was this collected?

Lone Star female, engorged..Molting?? Cannot make out the hard scutum.

Hi Bobbi - I was reviewing our CAP TMO survey and just noticed that you provided many of the photos used - very nice shots!
Hi RastaBob, glad you like the images! My friend Blaine (who regularly donates poems for my blog) is also on the CAP Microbiology Resource Committee and is now taking the lead on the TMO survey. So you'll be seeing pictures from him as well.
A. americanum female, partially engorged.
