This is interesting to know, there must be rumors going around about size, I was expecting anywhere beetween 4 and 6 inches for my chinese mantids that I hatched out of ooths that I purchased. I have been measuring all of my mantids from head(eyes without antennae) to tip of abdomen. I was expecting some long mantids :blink: . I guess I will find the truth some time. I found my first L4 this afternoon and I was expecting more, on account of what I had read previously about Tenodera sinensis. I think that perhaps some people measure other parts of anatomy when estimating length of the mantid.
