Well the sad truth is pretty much every mantid here was brought in this way, so the stories of endless seizures and DOA shipments are just a piece of the story, could be people not wanting the competition here, could be people bought from the wrong person, but every single nonnative species here in this hobby right now has came in this way whether in oothecae or live mantis.
The bigger question is the morals involved there have been some crackdowns and some people had seized packages even visits, letters some calls from Customs and F&W. The entire talk of it is bad for the hobby which is already regulated with laws that make it near impossible for us to even sustain a species here more than a few generations. I have to say it's not something I would venture into these days.
