My green ghost mantis has completed her adult molt last night and is truly a female (small antennae big thorax fan and slightly larger than her brown male counterparts. Nobody has said it out loud but it seems like the green ones are always female and the brown/black or tan ones are always males. If you look up photos of Ghost Mantids the greens always look this this - which is a female.
Here are some pics:
And of course some Tom Jones

I'm now going to work on planting up a 10 gallon vertical where I will move her in a few weeks after I've fed her all sorts of goodies to get her mice and fat then I will introduce the males to her enclosure and hope for some fertilized oothecas.
