Dionaea are fascinating plants. They have active traps (as opposed to passive traps like pitcher plants). I describe this more on my Dionaea page and also show this trap movement in a video I took. My mom showed me that The New York Times published an article highlighting a research study in the scientific journal, Nature Plants. It's so cool that there are scientists studying these mechanisms.
This is the full citation of the article:
Suda, H., Mano, H., Toyota, M. et al. Calcium dynamics during trap closure visualized in transgenic Venus flytrap. Nat. Plants 6, 1219–1224 (2020).
And here is one of many very cool videos of their work. You need special access for the entire article, but the supplementary videos are available at the bottom of their webpage.
