Moss Mimic Stick Insects performing a Ballet in Ecuador

This pair of moss mimic Stick Insects (nymphs of Trychopeplus thaumasius?) were filmed at Finca Palmonte near Baños in the cloud forest of Ecuador. During daytime they hang nearly imperceptible between moss covered twigs and only become active at night to feed on leaves, in this case an orchid leave. They not only look like moss but even move like waving in the wind. Here is another video of an adult:
