Mating aboreals

[ballpython2]

Do all taranturals mate on the ground or do aboreals mate on walls and the sort? or do aboreals mate up on horizontal tree branches??:?

The few times I have mated avics they tend to do the deed on the side of the glass, which can be funny because sometimes right when its about to get good one of them falls and the dance starts all over again.
My Obt mating I had the male fall a zillion times before he got it right.
They will mate on the ground too, and in one thread in the announcments section hes got them mating on his dang hand.
