Thank you everyone for being so thoughtful and helpful with your responses. Thank you @agent A
for your insight into mantis nutrition and thank you @The Wolven
for your honesty. Un/fortunately, I have not checked the forum since my last reply and went ahead and bought an H. membranacae since. Feeding has been difficult but possible but as I fed my mantis today I felt a deepening sense of guilt about the life I was forcing it to live. It was a self satisfying desire to own one and I considered my own desires over the mantis’ needs. I am going to have to do some soul searching over the next couple of days to decide what I can do, as I will either need to rehome it, or find my peace with feeding it live prey. I truly appreciate everyone’s support, understanding, and patience with me.
On another, more positive note, I also decided to purchase some hissers and feel good about keeping those. Made them a nice home and hoping to keep them for a long time!
Here’s some pics of my roaches, as well as some clips of me feeding my mantis today. It’s pretty labour intensive, as I need to continuously wiggle the string to emulate struggling prey to keep the mantis interested, else it drops the food (cut up piece of canned dubia). It really made me feel quite sad for it...
It didn’t finish the piece, but ate right around where the string was attached, which I found interesting. It may have been coincidence, but I also wonder if it was focusing its attention on the area from where it felt the most movement.
