Knock At The Cabin (2023)
In the scene where there’s a closeup of a grasshopper, prior to filming all grasshoppers were in holding. For this scene, production set up a frame on apple boxes with dirt, moss, and foliage. They filmed extreme close ups of one to three grasshoppers at a time. When ready to film, the handlers brought the grasshoppers to set. The trainer placed one grasshopper on foliage or dirt in the frame at a time. On action, the grasshopper performed its natural action.
When we see the little girl place grasshopper in jar, handlers were always nearby. Prior to shooting the actress was shown how to handle grasshoppers prior. Minimal grasshoppers used outside of jar scenes to help control them and not lose them. Natural action required from grasshoppers.
