On the ground underneath the willows another big green grasshopper, Schistocerca shoshone, was pushing her eggs into the loose sand of a dry part of the riverbed. She belongs to the Orthoptera suborder Caelifera and lacks an ovipositor. Instead, her abdomen can be elongated like a telescope. When she pulled it out of the sand, it was nearly 2 cm longer than her wings. In the image above left it is already partly contracted again. The images on the right were taken hours later and show the normal appearance of this bird grasshopper.
