...which is very similar to one by Kunihiko Kasahara in Creative Origami
Several people have pointed out that Ayture-Scheele appears to have plagarized Kasahara's and others' work. And I do agree. However, the color changed antennae is unique to her design, so I give her some credit.
Some people (e.g. me) may not consider this strict origami:
I made one cut to make the antennae. I think it makes a nice effect with the color change.
My wife had the plant in a display case, and I thought it would make a harmonious little scene.
