I've been searching it up, and it turns out that the massive poo (Horsehair parasite) does cause so much damage to the internal organs of the mantis to the point they die days after even if the parasite is removed fmllll 😭😭💔💔💔💔💔💔💔💔💔💔💔
Granted, there is still a small chance of survival, depending on the maturity of the parasite, the higiene the removal, and the health/age of the mantis
