Hello. I'm new to the forum and to mantids. I purchased an ooth as a science project for my kids (homeschool) three months ago and I was hooked. The ooth was Chinese and the mortality rate has been nearly 100%. I currently have one female L6/L7. This site has been sooooo helpful. I almost lost Gimp to illness (vomitting) when I found Rick's advice to another with the same complaint. Ditched the PetCo crickets and am sticking to moths for now. No more vomit! I am looking forward to expanding my collection. I've learned most of the basics the hard way with these Chinese nymphs and I'm ready to try something new!
