I’ve added branches for the YP to lay ribbons in over the years, but most of those haven’t worked. The YP seemed to prefer laying ribbons in the leaves. .

YP don't use branches to lay their eggs on if there are a lot of openings between the branches. Think of a Christmas tree that is 1-2 years old or a tumbleweed. Once the egg skein is on the bottom of the pond the eggs on the bottom don't get enough O2 to allow them to hatch.
