Strange thing happened last night. One of my grandis females laid her third ooth the other day. Well the day after she was very thirsty which was also out of the ordinary. She ate normally. Yesterday she looked ok physically however was acting a bit strange. Woke this morning to find her dead on the bottom of the cage. I got these on Jan. 14. The other two are fine. I generally don't have many problems with mantids however something isn't right when they die suddenly.
