Red velvet mite

Forgot to mention... you can identify this is Eutrombidium by, among other things, the presence of a small dorsal plate on the posterior end of the body (clearly visible in this photo). Body shape and the shade of red color are also helpful.

This is not a trombidiid. It is a microtrombidiid in the genus Eutrombidium (which used to be its own family, Eutrombidiidae, now recognized as a subfamily of Microtrombidiidae).

I think Karen is correct.. Red Velvet Mite... Its a tough Organism to spot as it is very active in speed and focusing is done after hard work of continuous follow it.

Not real sure what it is but maybe it starts around here: http://bugguide.net/node/view/91226
