I'm thinking its a Leaf Cutter ant.

Did you leave the tub inside or outside?

This is difficult for most species, most of the time. Some species queens will stay shallow at times (under rocks, or debris), and will make it easy in some instances. Just keep in mind, if you do find one from an established colony it will be very stressful and possibly mean the death of the queen...

It is kinda blurry at first but gets better, I found this in the Valley of Arizona, October 3rd.
