I recently had a P. paradoxa L3 nymph die unexpectedly after experiencing symptoms I have never seen before. At first, I thought it was going to molt as it had been refusing food (D. hydei) and was very stationary. It really didn't seem to be that uncommon; it looked like any other mantis that was about to molt. He was about due for a molt, too. The strange thing that's been happening for a few weeks now is that I've been finding this reddish colored liquid on the top of his enclosure wherever he decides to perch. I know it's coming from him because every time I open the lid to his container, I find more of the reddish colored discharge wherever he was sitting. Also, it seemed to be constantly increasing in frequency since I first realized that it had been happening. I didn't think much of it as he was still eating and molting just fine until I found him dead this morning.
