It is true, the beetle is the Regimbartia attenuata. There’s a paper on the idea of active escape post-predator-contact https://www.sciencedirect.com/science/article/pii/S0960982220308423
Although adult beetles were easily eaten by frogs, 90% of swallowed beetles were excreted within 6 h (0.1–6.0 h) after being eaten and, surprisingly, were still alive. When beetle legs were experimentally fixed with wax, all of the treated beetles were killed in the frogs’ digestive system and finally excreted >24 h (38.3–150.3 h) after consumption. Therefore, swallowed beetles likely used their legs to move through the digestive tract toward the frog vent, hastening their escape.

And if you relate more with the frog, then it’s a lesson in chewing your food properly.

Makes you wonder why only one beetle does this. Were the adaptions necessary to survive the digestive acid really complex or really unlikely, maybe?
