Yes! My armata don't seem to use the water pan for anything but a toilet! They will tip their heads and drink what runs down their snout. Or, as you described, they will form a place to collect water. Last week my female jumped down and drank from the water that accumulated in one of the oak leaves on the ground.
This morning I put in some fresh sphagnum moss behind the water pan when I noticed the largest female trying to squeese herself between that and the back wall of the viv. Next thing I knew she was in the middle of the moss while I was misting it. She hung her head over the side of the water pan and started lapping up the spray that was running down her snout. She looked very much like a Celtic dragon with her new gravid colors and markings. I wish I had my camera handy then!
By the time I left both females were on that fresh moss so I removed the male and non-gravid female to the other armata viv for the time being. Something has to give soon or the big girl is going to start spooking me!
