A Riemann surface equipped with its conformal hyperbolic metric is parabolic if and only if the geodesic flow on its unit tangent bundle is ergodic. Let
X
X
be a Cantor tree or a blooming Cantor tree Riemann surface. Fix a geodesic pants decomposition of
X
X
and call the boundary geodesics in the decomposition cuffs. Basmajian, Hakobyan, and Šarić proved that if the lengths of cuffs are rapidly converging to zero, then
X
X
is parabolic. More recently, Šarić proved a slightly slower convergence of lengths of cuffs to zero implies
X
X
is not parabolic. In this paper, we interpolate between the two rates of convergence of the cuffs to zero and find that these surfaces are not parabolic, thus completing the picture.
